Key Features & Benefits at a Glance
- Superior holding power with Class 3A thread fit for maximum engagement and vibration resistance in precision assemblies
- Excellent corrosion resistance provided by 303 Stainless Steel material, ideal for harsh industrial environments
- Precise ultra-fine threading (1/4"-100) ensures secure fastening in applications requiring minimal thread pitch
- Convenient installation and removal with 3/32" hex drive design, allowing easy access in confined spaces
- Enhanced gripping capability from the alloy steel ball tip that creates positive seating and reduces component slippage
- Headless design enables flush mounting without protrusion for streamlined machinery and equipment
- Full regulatory compliance with RoHS 3 and REACH standards for safe use in regulated industries
Professional Applications & Engineering Value
This precision set screw delivers critical performance in applications where ultra-fine threading and reliable clamping force are paramount. Engineered from 303 Stainless Steel, it resists corrosion in demanding environments while the Class 3A thread fit provides exceptional engagement for high-vibration machinery, precision instruments, and adjustable components. The headless design with hex drive allows installation in tight spaces where traditional fasteners can't operate, and the alloy steel ball tip bites into shafts and collars to prevent rotational slip. Ideal for securing gears, pulleys, and knobs in aerospace, automotive, and manufacturing equipment where thread integrity and compliance with RoHS/REACH standards are required.
Specification Summary & Compliance
This set screw features 1/4"-100 ultra-fine thread spacing with Class 3A fit per UNS standards, ensuring precise dimensional accuracy and thread engagement. The 3 3/4" length and right-hand thread direction provide versatile installation options. Manufactured in compliance with RoHS 3 (2015/863/EU) with exemption 6(c) and REACH (EC 1907/2006) regulations, meeting international environmental and safety requirements for industrial components.
