S-92845A545 1/4"-20 x 1" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments and reducing maintenance costs.
• Enhanced holding power thanks to the extended tip design (0.156" diameter) that bites deeper into materials for a secure, non-slip connection.
• High-strength durability with Rockwell B80 hardness, ensuring long-term performance under mechanical stress and vibration.
• Precise thread engagement with Class 3A thread fit, providing tighter tolerances for reliable assembly and reduced risk of loosening.
• Easy installation and removal using a standard 1/8" hex drive, allowing quick adjustments in confined spaces without specialized tools.
• Broad compatibility with UNC coarse threads (1/4"-20), making it versatile for various machinery and equipment applications.
• Compliance with industry standards including ASME B18.3, ensuring consistent quality and safety in professional settings.

Professional Applications & Engineering Value

This 1/4"-20 UNC set screw is engineered to address common challenges in industrial assemblies, such as component slippage and corrosion-induced failure. Made from 18-8 stainless steel, it resists rust and chemical exposure, extending service life in demanding environments like manufacturing equipment, automotive systems, and outdoor machinery. The extended tip and coarse thread design provide exceptional grip on shafts, pulleys, and collars, preventing unintended movement under high torque or vibration. With a headless and hex drive configuration, it enables flush mounting and easy access in tight spaces, streamlining maintenance and reducing downtime. Ideal for securing rotating parts, this screw meets rigorous standards to ensure reliability in B2B procurement for mechanical and engineering projects.

Specification Summary & Compliance

This set screw adheres to precise dimensional standards, including a Class 3A thread fit for superior accuracy and UNC coarse threads (1/4"-20) with a right-hand direction. It conforms to ASME B18.3 specifications for consistent manufacturing quality. Additionally, it is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring environmental safety and regulatory adherence for global industrial use.
