Product Description
5.5mm x 50mm Pozi Flange AB Self Tapping Screw BS 4174 - A2 | Vital Parts - ST4174-5.5-50-A2
Our 5.5mm x 50mm Pozi Flange AB Self Tapping Screw BS 4174 - A2 is part of our A2 stainless steel range of self tapping screws, designed for use where secure fastening into sheet metal, plastics or softer materials is required. The Pozi flange head provides a broader bearing surface to distribute load evenly, while the AB point style ensures clean and reliable penetration during installation.
What Are Pozi Flange AB Self Tapping Screws?
These screws conform to BS 4174 standards and are manufactured from corrosion-resistant A2 stainless steel. They feature a pozi (cross-shaped) drive for improved torque control and a flange head that eliminates the need for washers in many applications. The AB thread design allows quick starting and reduced driving torque.
Key Applications
- Automotive: Used in trim fixing, number plates and body panels.
- Construction & Joinery: Ideal for mounting hardware or brackets into pre-drilled holes in metal or plastic.
- Electrical Enclosures: Secure cable covers and component panels where anti-rust properties are required.
- General Assembly: Suitable for domestic, industrial and marine applications due to stainless steel corrosion resistance.
Why Choose This Screw?
Flange Head: Provides excellent clamping force and prevents pull-through.
Stainless Steel A2: Offers superior resistance to corrosion, suitable for outdoor or damp environments.
Pozi Drive: Minimises cam-out and allows for controlled installation with power tools or hand drivers.
