Beaver Jaw and Jaw Rigging Screw with Locknuts 10 mm, WLL 0.3 t (328310)

Beaver jaw and jaw rigging screws with locknuts are rated rigging hardware for straight, in-line tensioning with wire rope and chain assemblies, listed by Beaver with a working load limit (WLL) for each size. Beaver's manual heading gives BS 4429 (manufacturer-stated) and the finish as hot dipped galvanised. This listing carries six sizes, 10, 13, 16, 20, 24 and 38 mm, with WLLs of 0.3, 0.5, 0.75, 1.25, 2.5, 6 tonnes (manufacturer-stated). Beaver's range also lists 33 mm (5 t) and 50 mm (10 t).

A rigging screw is a tensioning device: the threaded ends turn in the body to take up or let out the length between the two end fittings. Beaver describes this type as made from high tensile steel, quenched and tempered, with a hot dip galvanised finish suitable for outdoor use, in metric sizes, and as suitable for industrial lifting purposes (manufacturer-stated).

Where this product is used

Working load limit and use

Beaver states its rated rigging hardware has a working load limit (WLL) and is rated for lifting applications, and that the rated load depends on the end fittings and thread (manufacturer-stated). Do not use the WLL as a guide for a different configuration, such as a hook end, which Beaver says has reduced capacity. Lifting equipment must be used within its marked working load limit (WLL), inspected before each use, and selected and used in line with your site lifting procedure and the relevant Australian Standards. If you are unsure what suits your lift, contact AIMS or a qualified rigger before ordering.

Securing the end fittings

Beaver's manual says turnbuckle end fittings must be secured, and gives this guidance (manufacturer-stated): to resist vibration, lock using wire; locknuts are not effective and add greatly to the load in the screw thread; when tightening, apply only the torque used for a bolt of equal size.

Key specifications

Codes, sizes, working load limits, dimensions (in millimetres), weights and pack quantities are from Beaver's Materials Handling Technical Manual (Vol. 4) and the Beaver website. Beaver does not define the dimension letters. Beaver sells the rigging screws singly (unit of measure: each).

Selecting the right option

Choose the size by the working load limit your application needs, then check the dimensions and the end fittings against your rigging. A qualified rigger should confirm the selection for any lifting application.
