UK Universal Self-Tapping Screw

FLOK supplies UK universal countersunk self-tapping screws with Pz recess, 2.5–6.0 mm diameter, 10–200 mm long, in carbon steel and stainless A2, A4.

The UK universal self-tapping screw is produced in various designs: with full or partial thread, shank diameter from 2.5 mm to 6 mm, length from 10 mm to 200 mm, made of different steel types. All variants share a common feature — a countersunk head with a Pz recess for use with a cross-head screwdriver or a power screwdriver fitted with the same bits. The UK screw is driven into wood materials, polymer parts and thin sheet metal without pre-drilling, directly along the marked line. After installation, the fastener head remains flush with the surface of the structure.

Universal self-tapping screws with countersunk head are made from several types of steel alloys. The most common are fasteners made of alloy steel, either uncoated or with an anti-corrosion coating in two color variants. A white tone indicates galvanic zinc plating, while yellow indicates the use of yellow passivation.

  • Carbon steel

Sizes of steel UK self-tapping screws with countersunk head: screw diameter from 2.5 to 6.0 mm, length from 10 to 200 mm.
