Detail & Specs
Flat head torx cap screws have a 90 degree angle underneath the head. When installed, the head of this screw is meant to sit flush with the surface of the work in a countersunk hole. Measured by overall length, including the head.
Torx drive screws provide higher torque transfer because the driving forces are transferred to each surface of the six lobes (wobble-free), instead of the four edges of the four edges on a phillips drive. Additional benefits include less wear on tools and no damage to the stainless steel surface coating.
Material: Stainless Steel
Suitable for damp locations
Corrosion resistant
Finish: Black Oxide
- Abrasion resistant, does not peel, chip or rub off
- Reduces friction, prevents galling
- Does not change the strength of the stainless steel
- Practically no dimensional change to base fastener
- The spray applied during the coating process wears off over time, revealing an attractive matte black finish
The black oxide coating per MIL-DTL-13924, Class 4 on 300 series corrosion resistant steel meets 96 hours of resistance in a 5% salt spray (fog) test in accordance with ASTM B117. We recommend using stainless steel installation tools to prevent extraneous rust.
