Description
Overview:
This is a Genuine Villiers bolt for vintage engine assembly and upkeep. Manufactured from strong steel, it uses a 1/4 inch UNC thread (6.35 mm diameter, coarse 20 TPI, approx. 1.27 mm pitch) for dependable fastening of engine components. It suits Villiers MK10/2 and MK12/2 series engines, helping maintain correct fit and alignment during rebuilds or routine maintenance. As unused old stock (NOS), it may show minor tarnishing consistent with age, but remains fully serviceable. Ideal for restorers and owners seeking original-spec parts that match the thread form and tolerances of classic Villiers engines, this bolt supports reliable clamping forces and helps preserve authenticity on machines where correct UNC hardware is essential.
