S-92695A837 5/8"-18 x 1" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-oxide coating, extending service life in harsh industrial environments.
• Exceptional holding power from the 90° cone point design, preventing component slippage under high vibration.
• Precise thread engagement with Class 3A UNF fine threads, ensuring reliable, vibration-resistant fastening.
• High-strength performance backed by Rockwell C45 hardness and alloy steel construction for heavy-duty applications.
• Easy installation and removal using the 5/16" hex drive, compatible with standard tools for efficient maintenance.
• Space-saving headless design ideal for confined assemblies where protruding fasteners are not feasible.
• Regulatory compliance assurance meeting ASME B18.3, ASTM F912, RoHS 3, and REACH for global supply chain suitability.

Professional Applications & Engineering Value

This black-oxide alloy steel set screw addresses critical engineering challenges in machinery, automotive, and precision equipment assembly. The UNF fine threads (5/8"-18) and Class 3A fit provide superior resistance to loosening under dynamic loads, while the 90° cone point bites securely into shafts and collars, eliminating positional drift. The Rockwell C45 hardness ensures durability against wear, and the black-oxide surface treatment offers reliable corrosion protection without compromising dimensional accuracy. Ideal for permanent or semi-permanent fastening in high-stress environments, this screw delivers consistent performance where vibration resistance and precise alignment are paramount.

Specification Summary & Compliance

This set screw maintains Class 3A thread tolerances per UNF standards with a 5/8"-18 fine thread and 1" length. Manufactured in compliance with ASME B18.3 and ASTM F912 specifications, it is verified for RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in industrial and export markets.
