Key Features & Benefits at a Glance
- Exceptional holding power with Class 3A thread fit ensuring reliable, vibration-resistant fastening in demanding applications
- Superior corrosion resistance from the black-oxide coating on alloy steel, extending service life in harsh industrial environments
- High-strength durability with Rockwell C45 hardness providing excellent resistance to wear and deformation under heavy loads
- Easy installation and removal using a standard 3/16" hex key, offering convenient maintenance and adjustments
- Space-saving headless design allowing flush mounting where protruding fastener heads are not feasible
- Precision-engineered UNC coarse threads delivering faster assembly and reduced cross-threading risk compared to fine threads
- Regulatory compliance assurance meeting ASME B18.3 specifications and environmental standards including RoHS 3 and REACH
Professional Applications & Engineering Value
Engineered for maximum holding power in industrial machinery, this black-oxide alloy steel set screw solves critical fastening challenges where vibration resistance and positional security are paramount. The 3/8"-16 UNC coarse threads with Class 3A precision fit create superior engagement in components like shafts, collars, and pulleys, preventing slippage under torque and dynamic loads. The headless hex drive design enables flush installation in confined spaces while maintaining high Rockwell C45 hardness to withstand repeated adjustments without thread deformation. Ideal for heavy-duty applications in manufacturing equipment, automotive assemblies, and power transmission systems where reliability cannot be compromised.
Specification Summary & Compliance
This set screw maintains Class 3A thread tolerances per UNC standards with 3/8"-16 coarse thread spacing and 1/4" length. Manufacturing conforms to ASME B18.3 specifications (ASTM F912) with full compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The flat tip design ensures concentrated clamping force while the right-hand thread direction follows industry-standard installation practices.
