Professional Applications & Engineering Value

This PTFE plastic slotted pan head screw solves critical engineering challenges in chemical processing, food equipment, and electrical enclosures where metal fasteners would corrode or contaminate products. The 1/4"-20 UNC coarse thread design maintains secure fastening in plastic assemblies and soft materials, while the fully threaded construction ensures maximum engagement strength. The white PTFE material provides natural lubricity that prevents galling and seizing in high-temperature applications up to 500°F, making it ideal for oven components, laboratory equipment, and semiconductor manufacturing where thermal cycling and chemical exposure are constant concerns. The rounded pan head profile with slotted drive offers both aesthetic cleanliness and practical installation in tight spaces.

Specification Summary & Compliance

This fastener features precision 1/4"-20 UNC coarse threads with Class 2A fit tolerance for consistent engagement. Manufacturing follows ASME B18.6.3 specifications for dimensional accuracy in head diameter (0.492"), head height (0.144"), and overall length (3/8"). The product is fully compliant with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations for chemical safety, ensuring global regulatory acceptance for industrial applications.
