These are genuine Flexifoil replacement parts or are of the same grade.** Pack of two with split spring lockwashers.

12 x 120 mm (we have seen them ship 130 mm and they work).  Thread pitch = 1.75

High tensile steel (Grade 8.8), not stainless, to help prevent galling (seizing).  You should still assemble with copper grease on the threads for good measure.

**Note:  Some of our buggy hardware parts are sourced locally but to the same grade and engineering specifications as the original parts.  We buy only from commercial industrial suppliers (no hardware-store-grade here) who know how to source, identify and supply parts of the proper grade, quality and specifications.  This is done with Flexifoil's knowledge and support, since they know that it is not always practical to source parts from the UK to the 'States.
