⚡ At a Glance
- • Holding Strength: Secure joins in exterior assemblies, supported by user feedback on reliability
- • Best for: Outdoor and high-moisture environments such as exterior trims and wet areas
- • Not ideal for: Applications requiring a flush countersunk finish due to the flanged head
Made from corrosion-resistant A2-70 stainless steel, these are Pozi flanged self-tapping screws. The outer diameter is 4.2mm with a 19mm length excluding the head, suitable for damp and outdoor use.
Long-lasting corrosion resistance - thanks to A2-70 stainless steel
A2-70 stainless steel is specified for corrosion resistance in moist conditions and resists surface rust. The grade indicates suitability for general outdoor use where exposure to moisture is common.
Reduced risk of corrosion means fixings remain serviceable for longer in wet environments, lowering the need for early replacement.
Firm, reliable installation - with Pozi flanged self tapping head
Pozi drive gives positive screwdriver engagement that reduces cam-out during installation, while the flanged head increases bearing area under the head. Self tapping threads cut their own mating thread as they are driven in.
Fast, repeatable installation and strong clamping force make these well suited for exterior trims and assemblies where a consistent fix is required.
Neat, controlled penetration - with 4.2mm diameter and 19mm length
An outer diameter of 4.2mm combined with a 19mm length (excluding the head) limits how far the screw penetrates. The shorter length reduces the risk of protruding through thin substrates.
Useful for fastening thin panels, trims or metal-to-wood joints where avoiding through-drill is important.
✨ The 4 Key Reasons for Bolt Base Stainless Steel Pozi Flange Self Tapping Screws
- A2-70 Stainless Steel - Corrosion resistance for humid and coastal environments over extended periods
- Pozi Drive Head - Positive engagement reduces cam-out and speeds up installation
- Flanged Head - Wider bearing surface prevents pull-through in soft materials
- Compact 19mm Length - Short length avoids piercing thin panels, ideal for trims
