Key Features & Benefits at a Glance
- Superior holding power with Class 3A thread fit ensuring tight, secure fastening in demanding applications.
- Excellent corrosion resistance provided by zinc plating on alloy steel, extending service life in harsh industrial environments.
- High durability and wear resistance from Rockwell C45 hardness, maintaining performance under repeated use and stress.
- Easy installation and removal with a 1/16" hex drive, allowing for efficient assembly and maintenance without slippage.
- Reliable alignment and minimal surface damage thanks to the cup tip design, ideal for precision components.
- Wide compatibility with 6-32 UNC coarse threads, ensuring easy integration into standard industrial assemblies.
- Compliance with major standards including ASME B18.3, RoHS 3, and REACH, guaranteeing safety and regulatory adherence.
Professional Applications & Engineering Value
This 6-32 UNC set screw is engineered to address common industrial challenges such as component slippage and corrosion in machinery. Made from zinc plated alloy steel, it offers robust protection against rust, making it suitable for automotive, aerospace, and manufacturing equipment where exposure to moisture is a concern. The Class 3A thread fit and coarse thread spacing provide a precise, vibration-resistant hold, reducing the need for frequent retightening in high-stress applications like motor shafts and gear assemblies. Its headless design and cup tip ensure flush mounting and minimal marring on surfaces, preserving the integrity of precision parts. By incorporating right-hand threads and a hex drive, it streamlines installation in tight spaces, enhancing productivity and reducing downtime in B2B operations.
Specification Summary & Compliance
This set screw adheres to ASME B18.3 specifications, with precise Class 3A thread fit for accurate dimensional tolerance in UNC threads. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material integrity. The construction meets industrial standards for durability and performance in various applications.
