-
Material: A2-70 (304) ≥ 700 MPa tensile; optional A4-80 (316) ≥ 800 MPa for coastal or chemical environments
-
Head: Countersunk 90° (DIN 7991 form) – sits flush or slightly below surface; decorative or hidden fixings
-
Drive: Torx T10–T30 – 6-lobe contact gives 40% more torque than Phillips, zero cam-out, perfect for impact drivers
-
Thread: Type-C (wood) with 45° gimlet point – wide, deep thread for maximum pull-out resistance; optional hi-low or twin-lead
-
Dia. & Length: #6 (3.5 mm) – #12 (5.5 mm) × 20 mm – 120 mm (3/4" – 4 3/4")
-

Salt-Spray: > 1,000 h (ASTM B117) on A2; > 1,500 h on A4
-
Temp. Range: –40 °C to +300 °C with full corrosion resistance
✔ Invisible Finish – head disappears below timber surface; plug or filler covers the drive recess for hidden joints
✔ High Pull-Out Strength – deep Type-C thread grips hardwood and engineered boards without stripping fibres
✔ Marine-Grade Rust Protection – no bleeding or staining on teak, iroko or composite decking
✔ Tool Efficiency – Torx drive transmits full driver power; reduces cam-out and bit wear
-
Mill test certificate EN 10204 3.1 supplied for every heat
-
RoHS & REACH compliant (passivation only)
-
Salt-spray & torque report provided per batch
-
Factory: ISO 9001 & IATF 16949, 15-year stainless fastener experience
