Professional Applications & Engineering Value

These 6-32 UNC zinc-plated steel rounded head slotted screws are engineered to address common industrial fastening challenges, including corrosion in humid or chemical-exposed environments. The zinc plating acts as a sacrificial layer, significantly extending service life compared to uncoated alternatives. With coarse thread spacing and full threading, they provide superior pull-out resistance in soft materials like plastics and wood, while the Rockwell B69 hardness ensures the screw maintains its form under repetitive torque applications. Ideal for electronics enclosures, machinery panels, and automotive assemblies, these screws deliver consistent performance where vibration resistance and thread reliability are critical. Their compliance with ASME B18.6.3 guarantees dimensional accuracy, reducing the risk of cross-threading and assembly errors in high-volume production lines.

Specification Summary & Compliance

These screws feature a Class 2A thread fit per UNC standards, ensuring proper clearance and tolerance for reliable engagement. The 1/8" length and 0.138" thread diameter provide precise dimensional control as specified. Manufacturing and material compliance include ASME B18.6.3 for mechanical and dimensional standards, RoHS 3 (2015/863/EU) for restricted substance adherence, and REACH (EC 1907/2006) for chemical safety, making them suitable for regulated industries and international markets.
