Professional Applications & Engineering Value
This precision 2-56 UNC set screw delivers exceptional engineering value in industrial applications where vibration resistance and secure positioning are critical. The 18-8 stainless steel construction provides excellent corrosion resistance, making it ideal for machinery, automotive components, and electronic enclosures exposed to harsh environments. The hex headless design allows for flush mounting in space-constrained applications while the 90° cone point ensures maximum grip by concentrating pressure on a small contact area. With Class 3A thread fit and coarse UNC threading, this set screw maintains precise alignment and prevents loosening under dynamic loads, solving common industrial fastening challenges in precision equipment and mechanical assemblies.
Specification Summary & Compliance
This 1/4" length set screw features precision Class 3A thread fit with 2-56 UNC coarse threads and right-hand thread direction. Manufactured to ASME B18.3 specifications with a cone point angle of 90° and Rockwell B80 hardness. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors.
