Professional Applications & Engineering Value
This nylon plastic set screw delivers critical engineering advantages where metal fasteners would compromise performance. The non-conductive properties make it ideal for electrical enclosures, electronic assemblies, and sensitive instrumentation where electrical isolation is paramount. The 1/4-20 UNC coarse thread provides excellent holding power in plastic housings and soft materials, while the flat tip design ensures secure positioning without damaging shafts or components. Engineers specify this headless set screw for applications requiring corrosion-resistant fastening in chemical environments, food processing equipment, and marine applications where metal corrosion would cause failure. The 1/8" hex drive allows for secure installation with standard tools while maintaining the screw's compact profile.
Specification Summary & Compliance
This set screw features 1/4"-20 UNC coarse threads with Class 2A thread fit ensuring proper clearance and engagement according to unified thread standards. The 3/4" length and 0.25" thread diameter provide standardized dimensions for consistent application across industrial uses. Manufactured from high-grade nylon plastic with off-white color and flat tip configuration, the fastener complies with RoHS 3 (2015/863/EU) environmental regulations, containing no restricted hazardous substances for global market acceptance.
