Professional Applications & Engineering Value

This 5/16" silver corrosion-resistant tapping screw solves critical challenges in masonry and concrete fastening applications. The external hex drive provides superior torque transmission compared to standard drives, preventing cam-out during installation in dense materials. Engineered with class 2A thread tolerances and a pointed tip, it creates precise mating threads in pre-drilled holes without requiring separate anchors. The silver corrosion-resistant coating on steel construction ensures long-term performance in environments exposed to moisture and chemical exposure, while the 2-3/4" length and 2" thread length provide optimal engagement depth for structural integrity in block, brick, and concrete substrates.

Specification Summary & Compliance

This tapping screw features inch system measurements with Class 2A thread tolerances and right-hand thread direction. Manufactured to industry standards for concrete anchoring applications, it complies with relevant mechanical performance specifications. The product meets RoHS and REACH environmental compliance requirements for restricted substances. Thread diameter: 0.313", length: 2-3/4", with flange diameter: 0.54" and head width: 5/16" dimensions ensuring proper fit and function in designated applications.
