Crafted from 18-8 (A2) stainless steel, these screws deliver excellent corrosion resistance and reliable performance in mildly corrosive environments. The Phillips drive ensures quick, familiar installation, and the 82° flat head design provides a flush, low-profile finish perfectly suited for a wide variety of assemblies.

Standard vs. Undercut (UC) Variants

Standard 82° Flat Head: Features a fully tapered underside, suitable for typical flush-mount applications using standard countersinks.

Undercut (UC) 82° Flat Head: Has a shorter head profile allowing the screw to sit fully flush in shallower countersinks. This variant is ideal for attaching door hinges, working with thin materials, or any scenario requiring a completely flush, secure fit.
