Hook and Eye Bolts - Lifting Eye Bolts - UNF

We stock Dynamo eyebolts for straight lifting and Collared eyebolts which are more suitable for angular lifting. The Dynamo eyebolts have a larger eye than the Collared option but have a smaller safe working load (SWL).

As with all fasteners, it is the responsibility of the user to ensure that the correct fitting is used for the application in question – and this is of paramount importance when considering lifting bolts. Many factors play a part in determining the SWL including the positioning and integrity of the anchoring point. Test certification is supplied with our lifting bolts.

Most of our lifting bolts are available in a self-colour finish, with a small amount of availability in zinc plated and stainless steel.

Choose from metric and imperial thread options.

UNF stands for Unified National Fine. It is a common imperial thread type with more threads per axial distance than its UNC equivalent.

Unified thread types (UNF and UNC) were introduced at the beginning of World War 2 to enable the interchangeability of machinery manufacturing between the USA, Canada and Great Britain. Still commonly found on a vast array of old machines and vehicles in the UK, UNF and UNC threads continue to be the standard thread in the USA and Canada.
