Professional Applications & Engineering Value

These 410 stainless steel tapping screws are engineered specifically for concrete, brick, and block applications where corrosion resistance and structural integrity are paramount. The pointed tip design facilitates easier penetration into masonry materials, while the standard flat head profile with 82° countersink angle ensures flush installation for clean, professional finishes. The combination of 1-5/8" thread length and right-hand threading provides optimal grip in dense substrates, addressing common challenges of loosening under vibration and environmental stress. These masonry screws deliver consistent performance in commercial construction, industrial facilities, and infrastructure projects where reliable anchoring in 3,000 psi concrete is essential for long-term structural stability.

Specification Summary & Compliance

Manufactured to precise dimensional standards with 1/4" thread diameter and 2-1/4" overall length, these tapping screws feature standard inch measurements for compatibility with North American construction practices. The flat head design incorporates an 82° countersink angle matching standard drill bits, while the 3/16" drill bit requirement ensures proper hole sizing for maximum holding strength. Compliance with RoHS 3 (2015/863/EU) regulations guarantees environmental safety, making these screws suitable for projects requiring sustainable building materials and regulatory adherence.
