Description
Overview:
Leaf Spring Bolt M12 x 80mm Thread Length, Grade 10.9 (MPN 763 050) is a high‐tensile fixing for mounting and retaining trailer leaf springs and associated brackets. It uses an M12 metric thread (12 mm diameter, approx. 0.47 in) with a thread length of 80 mm (approx. 3.15 in), making it suitable wherever an M12 x 80 fastener is specified on suspension joints. The 10.9 material grade provides high clamping force and durability under repeated dynamic loads typical of towing, site work and plant transport. This bolt is commonly used on single and double leaf spring arrangements on Ifor Williams trailers, and it is also found on some trailer coupling heads that require an M12 x 80 fixing. Intended as a like‐for‐like replacement during service and repair, it supports reliable alignment and securement of spring eyes, shackles and related hardware. Always match the original dimensions and strength grade, and tighten to the trailer manufacturer's recommended torque.
