Key Features & Benefits at a Glance
- Superior holding power with precision 10-32 UNF Class 3A fine threads for reliable, vibration-resistant fastening in demanding applications.
- Excellent corrosion resistance due to high-quality brass material, ensuring longevity in harsh or humid industrial environments.
- Easy installation and removal with a 3/32" hex drive headless design, allowing flush mounting and access in tight spaces.
- Enhanced grip and minimal surface damage from the cup point tip, which bites securely into shafts and components without excessive marring.
- Consistent durability backed by Rockwell B55 hardness, providing resistance to wear and deformation under load.
- Broad regulatory compliance including ASME B18.3 standards, RoHS 3, and REACH, ensuring safety and environmental responsibility.
- Precision fit and interchangeability with Class 3A thread fit, offering tight tolerances for high-performance assemblies.
Professional Applications & Engineering Value
This 10-32 UNF brass set screw is engineered to address common industrial challenges such as component slippage, corrosion in sensitive equipment, and space constraints. The headless hex drive and cup point tip deliver maximum gripping force, preventing rotational movement in pulleys, gears, and collars. Made from brass, it resists galvanic corrosion and is ideal for electrical components, marine hardware, and plumbing systems where non-sparking properties are valued. With Class 3A fine threads and Rockwell B55 hardness, it ensures repeated use without stripping, making it a reliable choice for precision machinery, automotive assemblies, and OEM manufacturing.
Specification Summary & Compliance
This set screw features a 10-32 UNF fine thread with Class 3A fit for high precision and strength. It complies with ASME B18.3 specifications, ensuring dimensional accuracy and performance. The product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting environmental and safety standards for hazardous substances.
