  • Headless hex drive design allows for flush mounting and secure, tamper-resistant fastening in confined spaces.
  • Class 2A thread fit with UNC coarse threading provides reliable, easy installation and consistent holding power.
  • RoHS 3 compliance meets stringent environmental regulations, ensuring safe use in global markets.
  • Durable nylon plastic construction offers lightweight strength and resistance to chemicals and wear.

Professional Applications & Engineering Value

This nylon plastic set screw is engineered to address common industrial challenges, such as corrosion in humid or chemical-exposed environments and electrical short-circuit risks in machinery and electronics. Its headless hex drive and UNC coarse thread design enable quick, secure fastening in tight spaces, reducing assembly time while providing a flush finish that prevents snagging. Made from off-white nylon, it withstands temperatures from -40° to 185°F, ensuring stability in applications like electrical enclosures, automotive components, and consumer electronics, where non-conductive, lightweight fasteners are essential for safety and efficiency.

Specification Summary & Compliance

This set screw adheres to UNC thread standards with a Class 2A fit for precise dimensional accuracy, featuring a 1/4"-20 thread size, 1" length, and flat tip for uniform contact. It complies with RoHS 3 (2015/863/EU) regulations, ensuring it is free from hazardous substances, and is manufactured to meet general industrial fastening requirements for reliability and performance.
