CLGR® Metric Collared Eyebolt BS 4278 Table 1, also called eye bolt metric collared.
Metric Collared Eyebolts BS 4278 Table 1 are typically used as removable lifting points where a rated female thread or nut is available. They can also serve as a termination for chains, wire ropes, and other assemblies when required.
Constructed from high-tensile steel 1045 and featuring a zinc-plated finish, these bolts are manufactured with a smaller eye compared to DIN-type bolts.
They conform to the BS4278 standard and are marked with the manufacturer's identification, axial and transverse working load limits in tonnes, direction indication arrows, thread type, nominal size, and batch number.
