Selectively hardened fasteners for attaching similar or dissimilar metals with Grade 5 screws.
Grade 5 Performance: Designed to attach similar or dissimilar metals, Teks Select fasteners have strength and ductility performance similar to Grade 5 Bolts. These characteristics in the fasteners load-bearing area improve resistance to shear failure due to wind and other loads requiring mechanical flex (ductility).
Selective Hardening: The drill point and lead threads are hard (HRC 52) enough to drill through steel. The load-bearing area remains soft (HRC 28-34) enough to remain ductile and resist hydrogen assisted stress cracking.
Climaseal ACR: Climaseal Advanced Corrosion Resistance coating enables Teks Select to out perform other selectively hardened fasteners in a 5% neutral salt spray.
Quick Start Drill Point and Efficient Self-Tapping Thread Design: These features combine to enable Teks Select to drill and tap up to 40% faster than other selectively hardened, drilling and tapping fasteners.
