Key Features & Benefits at a Glance
- Vibration-resistant locking with nylon patch thread locker prevents loosening under dynamic loads and thermal cycling from -50° to 250°F
- Exceptional durability from Rockwell C45 hardness alloy steel maintains thread integrity and resists wear in high-stress applications
- Precise thread engagement with Class 3A UNC coarse threads ensures reliable fastening and easier assembly in industrial equipment
- Corrosion-resistant black-oxide finish provides protection against oxidation in demanding environments
- Space-saving headless design with 3/16" hex drive allows flush mounting where clearance is limited
- Industry-standard compliance with ASME B18.3 guarantees dimensional accuracy and interchangeability
- Environmental responsibility through RoHS 3 and REACH compliance meets global regulatory requirements
Professional Applications & Engineering Value
This black-oxide alloy steel set screw delivers critical holding power in machinery, automotive, and manufacturing applications where vibration resistance is paramount. The nylon patch thread locking system maintains clamp load without compromising the Class 3A UNC coarse thread integrity, eliminating the need for secondary locking mechanisms. Engineered with Rockwell C45 hardness and coarse thread spacing, it withstands repeated adjustment cycles while the headless hex design provides reliable torque transmission in confined spaces. The combination of high-temperature resistance (-50° to 250°F) and corrosion protection makes it ideal for permanent installations in demanding industrial environments.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with Class 3A thread fit for precision dimensional control. Features UNC 3/8"-16 coarse threads with right-hand orientation and 3/4" length. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards. The nylon patch thread locker provides consistent locking performance across the specified temperature range while maintaining full disassembly capability.
