Professional Applications & Engineering Value
Engineered for precision and durability, this rounded head slotted screw excels in demanding industrial settings where corrosion resistance and mechanical strength are critical. The 18-8 Stainless Steel construction, enhanced by a passivated finish, effectively combats oxidation and chemical exposure, extending service life in electrical enclosures, machinery assemblies, and outdoor equipment. Its UNC coarse threading and Class 2A fit facilitate rapid installation with reduced cross-threading risks, while the binding head profile distributes clamping force evenly, preventing damage to connected components. This makes it an ideal industrial fastener for applications requiring secure, vibration-resistant connections without frequent maintenance.
Specification Summary & Compliance
This screw adheres to ASME B18.6.3 specifications, ensuring precise dimensions including a 1/4"-20 UNC thread with Class 2A tolerance for consistent fit. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming it is free from hazardous substances. The fully threaded design and Rockwell B100 hardness further support its reliability in standardized industrial applications.
