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. The flush-fitting countersunk head provides a neat, snag-free finish, while the nyloc nut locks securely against vibration without additional thread-locking compounds. Shorter than the M4 x 30mm variant, this kit is ideal for thinner materials and compact assemblies.

- Material: A2 (304) Stainless Steel

Well-suited for RC car builds, electronics panels, light fabrication, and general engineering where a clean flush fixing with vibration resistance is required. A2 stainless steel offers reliable corrosion resistance for indoor and outdoor use.
