M4 x 20mm Countersunk Screws with Nyloc Nut & Washer - A2 Stainless Steel - Pack of 4

A complete M4 x 20mm fastener kit featuring Pozi countersunk machine screws with matching A2 stainless steel nyloc nuts and washers.

Shorter than the M4 x 30mm variant, this kit is ideal for thinner materials and compact assemblies.
