Key Features & Benefits at a Glance
- Exceptional dimensional stability with Class 3A thread fit for minimal backlash and reliable assembly performance
- Superior wear resistance thanks to Rockwell C32 hardness, extending service life in high-stress applications
- Precise component alignment ensured by the 1/4" shoulder diameter with tight tolerance control
- Optimized for fine adjustments through 10-32 UNF right-hand fine threads providing superior clamping force
- Space-saving headless design with slotted drive for installations where clearance is limited
- Enhanced corrosion protection via alloy steel construction meeting stringent RoHS 3 and REACH compliance
- Reduced assembly errors with consistent shoulder length and diameter tolerances for repeatable precision
Professional Applications & Engineering Value
This 10-32 UNF precision shoulder screw delivers critical solutions for industrial automation, precision machinery, and optical equipment where exact component positioning is paramount. The alloy steel construction combined with Rockwell C32 hardness withstands repetitive loads and vibrational stresses, preventing premature failure in dynamic environments. Its Class 3A thread fit and precise shoulder dimensions eliminate play in rotating assemblies, ensuring accurate alignment of bearings, gears, and linkages. The headless slotted drive design facilitates compact installations while maintaining accessibility for adjustments. By integrating fine thread spacing with rigorous tolerance controls, this fastener reduces rework rates and enhances overall equipment reliability in precision grade fastener applications.
Specification Summary & Compliance
Manufactured to exacting standards with Class 3A thread fit per UNF specifications, featuring 10-32 fine threads with right-hand orientation. Shoulder diameter maintains 1/4" with -0.001" to 0" tolerance, while shoulder length holds 1/8" with 0" to 0.005" tolerance for precise fit applications. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures safe integration across regulated industries.
