Key Features & Benefits at a Glance
- Corrosion-resistant nylon construction eliminates rust and galvanic corrosion, ideal for electrical and marine environments
- Precision Class 2A thread fit ensures reliable, vibration-resistant fastening in fine-thread applications
- Wide temperature tolerance (-40° to 185°F) maintains integrity in fluctuating industrial conditions
- Headless hex drive design allows flush mounting in tight spaces while providing secure 1/8" tool engagement
- Non-conductive and non-magnetic properties prevent electrical interference in sensitive equipment
- RoHS 3 compliance meets stringent environmental regulations for global industrial use
- Flat tip configuration delivers maximum surface contact for secure positioning of components
Professional Applications & Engineering Value
This nylon plastic set screw delivers exceptional value in applications where metal fasteners would compromise performance. The UNF fine thread with Class 2A fit provides superior resistance to vibrational loosening in precision assemblies, while the off-white nylon material offers excellent dielectric properties for electrical enclosures and electronic components. The headless hex drive design enables seamless integration in confined spaces where protrusions are unacceptable. Engineers specify this corrosion-resistant fastener for machinery requiring non-conductive components, food processing equipment needing chemical resistance, and outdoor applications where temperature fluctuations from -40° to 185°F would degrade metal alternatives.
Specification Summary & Compliance
This set screw features 1/4"-28 UNF fine threads with Class 2A thread fit tolerances per unified thread standards. The right-hand thread direction and flat tip configuration ensure consistent performance across industrial applications. Manufactured from premium nylon plastic with 1/8" hex drive compatibility. Fully compliant with RoHS 3 (2015/863/EU) environmental regulations, making it suitable for global industrial distribution and use in regulated industries.
