Key Features & Benefits at a Glance
- Superior corrosion resistance with 316 Stainless Steel construction, ideal for harsh industrial environments and chemical exposure
- Precise, vibration-resistant locking achieved through Class 3A thread fit and extended tip design for secure component positioning
- High mechanical strength with Rockwell B80 hardness, ensuring durability under repeated adjustments and heavy loads
- Easy installation and removal with 5/64" hex drive, allowing efficient maintenance with standard tools
- Reliable coarse threading (UNC) that resists loosening in high-vibration applications and simplifies alignment
- Compact, headless design for space-constrained assemblies where flush mounting is required
- Compliance with global standards including ASME B18.3, RoHS 3, and REACH for safe, regulated use across industries
Professional Applications & Engineering Value
This 8-32 UNC set screw in 316 Stainless Steel addresses critical engineering challenges in machinery, automotive, and precision equipment. Its extended tip and Class 3A thread fit provide exceptional grip on shafts and collars, preventing slippage in high-torque or vibrating systems. The hex drive ensures straightforward installation with common Allen wrenches, reducing assembly time. As a headless set screw, it maintains a low profile in compact designs, while the coarse thread spacing enhances resistance to loosening. Ideal for permanent or semi-permanent fastening in corrosive environments, it supports long-term reliability with minimal maintenance.
Specification Summary & Compliance
This set screw adheres to ASME B18.3 specifications with a Class 3A thread fit for precise dimensional accuracy. Threading follows UNC standards with an 8-32 size and right-hand direction. The extended tip features a diameter of 0.109" and length of 0.043", manufactured within tight tolerances. It is fully RoHS 3 (2015/863/EU) and REACH compliant, meeting environmental and safety regulations for industrial use.
