Product Overview

Description

Our multipurpose 50mm countersunk self tapping screws are suitable for a wide variety of uses such as stitching metal sheets, attaching metal to metal, fixing wooden scructures, and many more. These colour matched screws feature a 60° self-tapping thread for ease of insertion into a pre-drilled hole, whilst the countersunk head gives a discreet finish into pre-countersunk holes.

Our RAL Painted 4.2mm Self Tapping Countersunk 50mm Screws are plated in Trivalent Chromium (Cr3) Zinc before being powder coated in any colour you need. They have a sharp AB point and a standard Pozi recess type, using a PZ2 driver bit size to aid installation.

Powder coated screws

Here at RALfixings we believe it's the little details that make the big picture. That's why we powder coat all our screws and fixings to any RAL colour your project requires. Powder coating involves spraying the fixings with a coloured powder, then super heating them to fuse this powder into a protective layer. Powder coat finishes are more durable than painted finishes. Powder coating can protect metal for as long as two decades.
