The Laser Tools 31404 is a specialized pack of 50 M10 Form C flat washers, offering a superior alternative to standard Form A variants when working with compromised or softer materials. In the UK automotive trade, Form C washers are highly valued for their significantly larger outside diameter and increased thickness compared to standard washers. This expanded footprint is vital when securing M10 bolts into aluminium engine mounts, thin-walled subframes, or heavy-duty plastic guards, as it distributes the fastener’s clamping force over a much wider area. This prevents the bolt head from "sinking" into the material or causing cracks under vibration. Each washer is forged from high-grade steel and finished with a robust zinc coating to ensure longevity in the damp UK climate. This 50-piece pack is ideal for technicians performing suspension upgrades or engine bay overhauls where consistent pressure and material protection are paramount for a professional finish.
