Key Features & Benefits at a Glance
- Enhanced Grip and Reduced Slippage – Permanent swivel tip with 7.5° maximum angle ensures secure contact on curved or uneven surfaces, minimizing component movement.
- Superior Corrosion Resistance – Black-oxide finish on alloy steel provides durable protection against rust in demanding industrial environments.
- High Mechanical Strength – Rockwell C45 hardness delivers excellent wear resistance and maintains thread integrity under repeated adjustments.
- Precision Thread Fit – UNC coarse threads with Class 2A tolerance enable quick assembly and reliable fastening without cross-threading risks.
- Space-Saving Headless Design – Flush installation allows use in confined spaces where protruding fastener heads are not feasible.
- Effortless Installation – 1/8" hex drive permits high-torque application using standard tools, reducing installation time and tool wear.
- Regulatory Compliance Assurance – Meets RoHS 3 and REACH standards, ensuring suitability for regulated industries and international supply chains.
Professional Applications & Engineering Value
This black-oxide alloy steel set screw addresses critical challenges in precision machinery and power transmission systems. The permanent swivel tip prevents damage to shafts and gears by distributing clamping force evenly, while the UNC coarse thread design resists vibration-induced loosening in high-RPM applications. Engineers specify this component for industrial set screws requirements where Rockwell C45 hardness ensures dimensional stability under cyclic loading. The headless configuration proves invaluable in conveyor systems and motor couplings where space constraints prohibit traditional fasteners. Combined with Class 2A thread fit manufacturing consistency, this hex drive set screw delivers repeatable performance in automated assembly environments.
Specification Summary & Compliance
Manufactured to UNC thread standards with Class 2A tolerance for precise fit. Complies with RoHS 3 (2015/863/EU) under exemption 6(a)-I and REACH (EC 1907/2006) regulations. Thread specifications: 1/4"-20 coarse pattern with right-hand orientation. Mechanical properties include Rockwell C45 hardness and permanent swivel tip construction with 0.156" tip length.
