Description
Overview:
Leaf Spring Bolt M12, 100mm Thread Length, Grade 10.9 (MPN 763 103) is a high-tensile metric fastener for trailer suspension work. It is intended for securing leaf spring eyes to hangers or shackle plates and for other M12 applications where a long threaded section is required. The bolt uses a standard M12 thread (12 mm diameter, approximately 0.47 in) with 100 mm (3.94 in) of thread length to suit common bush and bracket stacks on trailer running gear. Manufactured to property class 10.9, it provides the strength needed for suspension and drawbar-related fixings. This size is commonly specified on Ifor Williams trailers with single and double leaf springs and can also be used on some trailer coupling heads where an M12 x 100 thread is called up. It is a practical choice for workshops handling routine repair and overhaul of plant, livestock, tipper and general duty trailers.
