Professional Applications & Engineering Value

These Grade 5 hex head screws deliver critical performance where structural integrity matters most. The zinc-plated steel construction provides essential corrosion protection for industrial equipment, automotive assemblies, and machinery exposed to environmental elements. The 10-32 UNF fine threading with Class 3A precision ensures superior thread engagement in materials where coarse threading might compromise integrity. The flanged design eliminates the need for separate washers while distributing clamp load effectively, making these fully threaded screws ideal for applications requiring consistent tension along the entire fastener length. With 110,000 psi tensile strength, they withstand extreme mechanical stresses in heavy-duty fastening scenarios where failure is not an option.

Specification Summary & Compliance

Manufactured to exacting Class 3A thread fit tolerances with UNF specification fine threading (10-32 size). These hex head screws comply with IFI 111/SAE J429 mechanical and dimensional standards for Grade 5 fasteners. The 3/8" length and external hex drive configuration ensure consistent installation performance. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations guarantees safe use across regulated industries.
