• Environmental compliance meets RoHS 3 and REACH regulations for safe use in regulated industries

Professional Applications & Engineering Value

These 316 stainless steel Phillips truss head tapping screws are specifically engineered for demanding sheet metal applications where corrosion resistance and structural integrity are paramount. The thread forming design creates strong, permanent threads in parent material without chip formation, eliminating the need for separate tapping operations and reducing assembly time. The wide truss head profile provides superior bearing surface distribution, preventing material deformation in thin-gauge metals up to 0.025" thickness. Manufactured from marine-grade 316 stainless steel, these fasteners maintain performance in corrosive environments including chemical processing, marine applications, and outdoor installations. The combination of fully threaded shanks and precise A/AB thread form ensures maximum pull-out resistance and vibration resistance in metal fabrication, HVAC systems, and electronic enclosures.

Specification Summary & Compliance
