Key Features & Benefits at a Glance
- Superior corrosion resistance from nylon construction, eliminating rust and chemical degradation in harsh environments
- Excellent electrical insulation properties for safe applications in electrical/electronic assemblies
- Wide temperature tolerance (-40°F to 185°F) maintains performance across diverse operating conditions
- Precise Class 2A thread fit ensures smooth installation and reliable engagement with mating components
- Undercut flat head design provides flush mounting while maximizing head strength
- 82° countersink angle enables proper seating in standard chamfered holes
- Full threading along 2-1/2" length offers maximum adjustment flexibility and holding power
Professional Applications & Engineering Value
This nylon flat head slotted screw delivers critical advantages where metal fasteners fail. The non-conductive plastic construction prevents electrical shorts in control panels, electronic enclosures, and instrumentation. Its inherent corrosion resistance makes it ideal for chemical processing, marine, and food equipment where moisture and corrosive agents degrade metal alternatives. The UNC coarse threading provides rapid installation and superior pull-out resistance in plastic and soft materials. The undercut flat head profile distributes clamping force efficiently while maintaining a flush surface finish. These industrial plastic screws solve conductivity, corrosion, and weight challenges while meeting rigorous ASME B18.6.3 specifications for dimensional consistency.
Specification Summary & Compliance
Manufactured to ASME B18.6.3 standards with Class 2A thread fit tolerances for consistent performance. Features 1/4"-20 UNC coarse threads with right-hand direction and full threading along the 2-1/2" length. The 82° countersink angle matches standard chamfer specifications. Compliant with RoHS 3 (2015/863/EU) environmental regulations, containing no restricted hazardous substances.
