• Optimized for sheet metal with pointed tip and No. 21 drill bit compatibility for straightforward installation into materials up to 0.025" thick.
• Secure pan head design offers a low-profile, rounded head with good bearing surface for stable clamping force.
• Compliant with major regulations including RoHS 3 and REACH, ensuring safe use in regulated industrial and international markets.

Professional Applications & Engineering Value

These zinc-plated steel tapping screws are engineered specifically for sheet metal applications, where creating strong, reliable threads without pre-tapped holes is critical. The thread forming (Type A/AB) action cold-forms the material, resulting in zero chip production and a tight, vibration-resistant fit that prevents loosening under stress. The combination of a pan head with a Phillips/Slotted drive provides installation flexibility and a secure clamp. The fully threaded No. 10-12 design ensures maximum grip length, making these industrial screws ideal for HVAC assemblies, electrical enclosures, and automotive panels where durability and compliance are non-negotiable.
