Long-lasting corrosion resistance - with A2-70 stainless steel

Material is listed as A2-70 stainless steel and described as corrosion resistant in the product details. User feedback notes rust-free construction and durable finish.

Corrosion resistance reduces the need for frequent replacements in garden or coastal applications, so fixings remain reliable over time.

Secure clamping under load - with a flanged head

Flanged Pozi head is specified in the product name and descriptions, giving a wider bearing surface than a standard countersunk head. Reviews highlight well-engineered design and dependable craftsmanship.

Flange spreads clamping force across the material, helping to prevent pull-through on thinner panels and soft timbers.

Faster, neater installations - with Pozi drive and self-tapping thread

Described as Pozi flanged self tapping screws, the drive and thread are intended for direct engagement into appropriate substrates without separate thread-forming operations. Outer diameter is 4.2mm with 38mm length excluding the head.

Pozi drive and self-tapping threads speed up assembly for routine fixes, reducing time spent on pilot holes and speeding repetitive tasks.
