Key Features & Benefits at a Glance
- Corrosion-resistant nylon construction ensures reliable performance in humid or chemical environments without rust or galvanic corrosion.
- Precise Class 2A thread fit guarantees consistent engagement and secure fastening in UNC threaded components.
- Wide temperature tolerance (-40° to 185°F) maintains integrity across diverse operating conditions from freezing to elevated heat.
- Headless, slotted flat-tip design allows flush mounting and easy adjustment with standard screwdrivers in confined spaces.
- RoHS 3 compliance meets stringent environmental regulations for safe use in electronics and regulated industries.
- Coarse UNC threading provides rapid installation and strong holding power in plastic or soft material assemblies.
- Lightweight off-white nylon material offers electrical insulation and non-magnetic properties for sensitive applications.
Professional Applications & Engineering Value
Engineered for precision fastening in electrical enclosures, consumer electronics, and plastic assemblies, this 4-40 UNC nylon set screw solves critical challenges like component shifting and vibration loosening. The flat tip design applies concentrated pressure without damaging soft materials, while the Class 2A thread fit ensures repeatable accuracy in automated installations. Unlike metal fasteners, the off-white nylon plastic eliminates conductivity risks and resists chemicals, making it ideal for PCB mounts, medical devices, and outdoor equipment where weight, corrosion, and insulation are concerns. Its right-hand coarse threads deliver quick seating in thermoplastic housings, reducing assembly time while maintaining temperature resistance from sub-zero to moderate heat conditions.
Specification Summary & Compliance
This set screw adheres to UNC coarse thread standards with 4-40 thread size, 0.112" diameter, and 11/64" length. Manufacturing conforms to Class 2A thread fit tolerances for consistent dimensional accuracy. The product is fully RoHS 3 (2015/863/EU) compliant, containing no restricted hazardous substances, and is suitable for applications requiring right-hand threading and flat tip engagement.
