Professional Applications & Engineering Value
This alloy steel set screw delivers exceptional vibration resistance in industrial machinery, automotive components, and precision equipment where permanent fastening solutions are critical. The nylon patch thread locker creates a chemical bond that prevents loosening under dynamic loads, eliminating the need for secondary locking mechanisms. The extended tip design (0.25" diameter) provides superior biting action into mating parts, while the UNF fine thread configuration offers increased tensile strength and better load distribution compared to coarse threads. Engineered to ASME B18.3 specifications, this hex headless set screw ensures reliable performance in high-stress applications where space constraints and vibration are primary concerns.
Specification Summary & Compliance
This fastener features Class 3A external thread fit with UNF fine thread specification (3/8"-24). Manufactured to ASME B18.3 standards with Rockwell C45 hardness for optimal strength. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The extended tip configuration maintains precise tolerances with tip diameter of 0.25" (-0.009" to 0" tolerance) and tip length of 0.099" (-0.01" to 0" tolerance).
