Professional Applications & Engineering Value
Engineered for precision assembly in demanding industrial settings, these 4-40 UNC thread socket head cap screws deliver critical performance advantages. The 18-8 stainless steel composition provides excellent corrosion resistance, making them suitable for applications exposed to moisture, chemicals, or outdoor elements. The Class 3A thread fit ensures superior engagement in tapped holes, reducing the risk of cross-threading and maintaining clamping force under vibration. With coarse thread spacing and right-hand thread direction, these fasteners offer quick assembly in machinery, automotive components, and electronic enclosures where 70,000 psi tensile strength prevents failure under high stress. The combination of Rockwell B70 hardness and fully threaded design makes them ideal for applications requiring consistent clamping force across the entire fastener length.
Specification Summary & Compliance
This socket head cap screw features precision 4-40 UNC coarse threads with Class 3A thread fit for superior dimensional accuracy. Manufactured to ASME B18.3 specifications, ensuring consistent performance in inch system applications. The fastener is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, meeting the latest industry standards for hazardous substance restrictions.
