Professional Applications & Engineering Value
Engineered for demanding industrial settings, these 6-32 UNC left hand thread screws with a rounded button head and hex drive address critical assembly challenges. The 18-8 stainless steel material resists rust and chemical exposure, making them suitable for automotive, machinery, and marine applications where corrosion is a concern. The coarse thread spacing and Class 2A fit facilitate quick, reliable fastening in metals and plastics, reducing installation time and preventing cross-threading. Their left-hand thread direction is essential for components subject to counter-clockwise rotation, providing added safety in high-vibration environments. This combination of high tensile strength and Rockwell B85 hardness ensures long-term reliability, minimizing downtime and maintenance costs in professional engineering projects.
Specification Summary & Compliance
This screw adheres to UNC thread standards with a Class 2A thread fit for consistent dimensional accuracy. It features a coarse thread spacing, fully threaded design, and precise dimensions including a 0.262" head diameter and 3/4" length. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and suitability for global industrial markets.
