Professional Applications & Engineering Value
This zinc-plated alloy steel flanged button head screw delivers exceptional engineering value in industrial assembly where vibration resistance and structural integrity are paramount. The UNC Class 3A coarse threading provides superior engagement in softer materials and faster installation compared to fine-thread alternatives. The integrated flange design distributes clamping force over a wider surface area (0.563" diameter), preventing surface damage while eliminating separate washer requirements. With fully threaded construction and 120,000 psi tensile strength, these hex drive screws maintain secure fastening in high-stress applications including machinery, automotive components, and structural frameworks where reliability cannot be compromised.
Specification Summary & Compliance
This fastener features precision UNC 1/4"-20 coarse threads manufactured to Class 3A fit tolerances for consistent performance. The zinc-plated alloy steel construction provides optimal corrosion protection while maintaining Rockwell C32 hardness. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial applications requiring strict material compliance standards.
