Product Number: FWC821
Standard M8 washers can lack the clamping area needed for softer materials or oversized clearance holes, leading to pull-through and insecure fastenings. The Sealey FWC821 is a Form C metric flat washer in M8 x 21mm, offering a wider diameter than Form A and Form B washers to provide an increased clamping area and a more secure, distributed load. Manufactured to BS 4320 for consistent quality and dimensional accuracy. Supplied in a resealable bag in a convenient pack of 100, keeping unused washers organised and protected.
