Professional Applications & Engineering Value
Engineered for demanding industrial applications, these 2-56 UNC pan head screws address critical challenges in assembly and maintenance. The passivated 18-8 stainless steel provides superior resistance to oxidation and chemical exposure, extending service life in machinery, electronics, and outdoor equipment. The coarse thread design ensures quick, secure fastening in softer materials or where vibration loosening is a concern, while the Phillips drive facilitates efficient installation with standard tools. Fully threaded from head to tip, these screws deliver uniform clamping force, preventing joint failure and reducing the need for frequent retightening in high-stress environments.
Specification Summary & Compliance
This screw meets ASME B18.6.3 specifications for dimensional consistency, featuring a Class 2A thread fit for reliable engagement and UNC coarse threads with a size of 2-56. The 1 3/4" length and fully threaded profile ensure precise application fit. It is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming adherence to environmental and health standards without restricted substances.
