Key Features & Benefits at a Glance
- Exceptional tensile strength of 170,000 psi ensures reliable performance under high-stress conditions, reducing the risk of fastener failure.
- Precision Class 3A thread fit provides superior engagement and vibration resistance in critical assemblies.
- Black-oxide coating on alloy steel offers enhanced corrosion resistance and a durable, non-reflective finish.
- Fine UNRF threads deliver improved clamping force and better load distribution compared to coarse threads.
- Fully threaded design allows for consistent holding power along the entire length, ideal for adjustable applications.
- Hex socket drive enables high-torque installation with reduced risk of cam-out, saving time and tool wear.
- Compliance with ASTM A574, RoHS 3, and REACH ensures material consistency and environmental safety for global supply chains.
Professional Applications & Engineering Value
These black-oxide alloy steel socket head cap screws are engineered to address common industrial challenges such as vibration loosening and corrosion in demanding environments. The Class 3A thread fit and UNRF fine threads provide exceptional clamping force and fatigue resistance, making them ideal for precision machinery, automotive assemblies, and heavy equipment where reliability is critical. The fully threaded design ensures uniform stress distribution, while the high tensile strength and Rockwell C37 hardness prevent stripping and deformation under load. Suitable for applications requiring right-hand thread fasteners with consistent performance in inch measurements, these screws offer long-term durability and reduced maintenance costs.
Specification Summary & Compliance
This product features a 10-32 UNRF fine thread with Class 3A precision fit and a length of 1-1/2 inches. It meets ASTM A574 specifications for alloy steel socket head cap screws and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to international environmental and safety standards.
