Screw Hole (FE): professional lifting nuts for flexible lifting applications

Lifting nuts for safe lifting, turning and tilting

When lifting machines, moulds, structures and other heavy loads, a standard lifting eye is not always the most suitable solution. When a structure is equipped with a suitable threaded hole, a lifting nut can provide a practical and professional lifting solution.

The Screw Hole (FE) range from OpenSupply consists of various Codipro lifting nuts with a female connection. Depending on the model, these lifting nuts are available with single or double swivel and in metric, UNC and stainless-steel versions.

Especially when a load needs to move, rotate or tilt during lifting, a lifting nut with double swivel provides additional freedom of movement.

The result: a flexible lifting point that fits the existing construction and is suitable for a wide range of professional lifting applications.

What is a lifting nut with a screw hole?

A lifting nut with a screw hole is a lifting point with a female thread. Instead of a lifting eye with an integrated fixed bolt, the lifting nut is installed using a suitable connection in the structure.

Within the Screw Hole (FE) category, OpenSupply offers various Codipro solutions. This makes it possible to select a version that matches the required freedom of movement, working load and thread type.

The range includes, among others:

• lifting nuts with single swivel;

• lifting nuts with double swivel;

• metric versions;

• UNC versions;

• stainless-steel versions;

• versions for different working loads.

This makes the category suitable for various machines, structures and industrial applications where a female lifting connection is required.

The advantages of a female lifting connection

An important advantage of the FE versions is that the lifting point is designed as a lifting nut. This makes the products suitable for applications where a female connection is preferred or required.

This allows the lifting point to be matched to the existing construction.

Different movement options are also available within the range. Some models feature single swivel, while other versions have double swivel for applications where the load needs to move during lifting.

The correct version therefore depends not only on the working load, but also on the way in which the load needs to be lifted.

Double swivel for maximum freedom of movement

360° rotation and 180° tilting

An important product within the range is the FE.DSR. This lifting nut with double swivel is specifically designed for simultaneously lifting and turning loads.

The lifting ring can:

Rotate 360°
The ring can rotate all the way around, including when used under load.

Tilt 180°
The ring can tilt through a wide range and adapt to the direction of the load.

The double swivel movement allows the lifting ring to align more effectively with the lifting accessory during lifting.

The FE.DSR can therefore be used for various lifting configurations, including straight lifting, angled lifting, tilting and rotating.

FE.DSR: compact lifting nut with double swivel

The FE.DSR is one of the key products within the Screw Hole (FE) category.

The FE.DSR is available in metric versions from M8 to M22. Depending on the version, the working load reaches up to 3.5 tonnes at a safety factor of 5:1.

OpenSupply lists the FE.DSR with a maximum working load of 3.5 tonnes at SF 5:1 and a maximum metric nut size of M22.

The metric versions include:

• M8 – 0.40 tonnes;

• M10 – 0.70 tonnes;

• M12 – 1.05 tonnes;

• M14 – 1.40 tonnes;

• M16 – 2.00 tonnes;

• M18 – 2.30 tonnes;

• M20 – 2.50 tonnes;

• M22 – 3.50 tonnes.

In addition to the metric versions, the FE.DSR is also available with UNC thread. This version ranges from UNC 1/4" to UNC 7/8" and, depending on the version, has a working load of up to 7,900 lbs / approximately 3.6 tonnes.

FE.DSS: double swivel for heavier loads

When a higher working load is required, the FE.DSS provides a solution for heavier lifting applications.

The FE.DSS is a lifting nut with double swivel for higher loads. OpenSupply lists the metric version with a maximum working load of 19 tonnes at SF 5:1 and a maximum nut size of M52.

For applications with UNC thread, the FE.DSS UNC is also available. According to OpenSupply, this version has a maximum working load of 21 tonnes at SF 5:1 and is available for UNC sizes from 1/2" to 1".

This makes the FE.DSS a suitable solution when the capacity of an FE.DSR is not sufficient.

FE.SEB UP: lifting nut with single swivel

Not every application requires double swivel. For situations where a single swivel movement is sufficient, OpenSupply offers the FE.SEB UP.

The FE.SEB UP is a lifting nut with single swivel and, according to OpenSupply, has a maximum working load of 9 tonnes at SF 5:1. The maximum metric nut size is M36.

For applications with UNC thread, the FE.SEB UP UNC is available. This version has a maximum working load of 11 tonnes at SF 5:1 and is available for UNC threads from 3/8" to 1 1/2".

The FE.SEB UP is therefore particularly suitable for applications where a female lifting connection is required, but the additional freedom of movement of a double swivel is not necessary.

Also available in stainless steel

For applications where corrosion resistance is important, OpenSupply also offers stainless-steel lifting nuts with a female connection.

Within the Screw Hole (FE) category, the SS.FE.DSR and SS.FE.DSS are available, among others.

The SS.FE.DSR is a stainless-steel lifting nut with double swivel. OpenSupply lists this version with a maximum working load of 2.2 tonnes at SF 5:1 and a maximum nut size of M22.

For heavier applications, the SS.FE.DSS is available. This stainless-steel lifting nut with double swivel has, according to OpenSupply, a maximum working load of 5 tonnes at SF 5:1 and a maximum nut size of M36.

Stainless-steel versions with UNC thread are also available, including the SS.FE.DSR UNC and SS.FE.DSS UNC.

Metric or UNC thread?

One of the most important choices when selecting a lifting nut is the correct thread.

Within the Screw Hole (FE) range, both metric and UNC versions are available.

Metric thread

The metric FE versions are suitable for structures with metric threads. Depending on the model, different sizes are available, from compact versions to larger lifting nuts for higher loads.

UNC thread

For structures with UNC thread, specific versions are available, including the FE.DSR UNC, FE.DSS UNC and FE.SEB UP UNC.

The correct size depends on the existing mounting point and the required working load.

Always check that the thread, working load and version correspond to the intended application before using the lifting nut.

Single or double swivel?

The choice between a lifting nut with single or double swivel mainly depends on the movement required during lifting.

Single swivel

A version such as the FE.SEB UP is suitable when a single swivel movement is sufficient.

Double swivel

A version such as the FE.DSR or FE.DSS is particularly suitable when the load needs to rotate or tilt during lifting.

The double articulation provides greater freedom of movement and helps the lifting ring align with the lifting accessory.

Safety and technical quality

When lifting loads, it is essential to select the correct lifting point and take the maximum working load into account.

Codipro specifies safety factors of 4:1 and 5:1 for the different versions, depending on the model.

The FE.DSR is, according to Codipro, among other things:

• suitable for rotation under load;

• equipped with 360° rotation and 180° tilting;

• manufactured according to EN 1677-1;

• individually traceable;

• marked with, among other things, CE, WLL and tightening torque information;

• suitable for various lifting configurations from 0° to 90°, within the applicable product conditions.

The exact working load and safety factor vary by version. Always consult the technical documentation for the selected product.

Which lifting nut with screw hole do you need?

The range offers various possibilities. The most important questions when selecting the correct version are:

How heavy is the load?

The WLL (Working Load Limit) determines which version is suitable for the lifting operation.

Which thread do you need?

Check whether you require a metric or UNC version and which size matches the structure.

Does the load need to rotate?

If the load needs to rotate or tilt during lifting, a version with double swivel is particularly suitable.

Do you need a higher working load?

For heavier applications, the FE.DSS can provide a suitable solution.

Is single swivel sufficient?

When double swivel is not required, the FE.SEB UP may be a suitable choice.

Are you working in an environment where stainless steel is preferred?

In that case, consider the SS.FE.DSR or SS.FE.DSS and the corresponding UNC versions.
