Professional Applications & Engineering Value

This polypropylene socket head cap screw delivers exceptional value in applications where metal fasteners would corrode or contaminate sensitive environments. The UNC coarse thread design provides rapid installation and superior pull-out resistance in plastic components and soft materials. Engineered with a standard hex drive and Class 2A thread fit, this fastener ensures consistent torque transmission and reliable clamping force in assembly operations. The off-white polypropylene material offers excellent resistance to chemicals, moisture, and electrical insulation properties, making it ideal for electrical enclosures, food processing equipment, laboratory instruments, and marine applications where non-conductive, non-corrosive fastening solutions are critical.

Specification Summary & Compliance

This 1/4"-20 x 1-1/2" socket head cap screw features UNC coarse threads with Class 2A thread fit tolerance for precise engagement. The fastener maintains dimensional accuracy with a 3/16" hex drive, 3/8" head diameter, and 1/4" head height. Manufactured from durable polypropylene plastic in off-white color, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring safe use in regulated industrial applications.
