S-94564A225 1/4"-28 x 3/4" Set Screws

Key Features & Benefits at a Glance

• Excellent chemical resistance from nylon plastic construction, ideal for corrosive environments
• Reliable temperature performance from -40° to 185°F, maintaining integrity in varied operating conditions
• Precise Class 2A thread fit ensures secure fastening with minimal vibration loosening in fine-thread applications
• Compact headless hex drive design allows for flush mounting in space-constrained assemblies
• RoHS 3 compliance meets environmental regulations for global manufacturing and supply chain requirements
• Flat tip design provides consistent surface contact for secure component positioning without damage
• Lightweight off-white nylon material offers electrical insulation and corrosion resistance without metallic contamination

Professional Applications & Engineering Value

This 1/4"-28 UNF nylon set screw delivers critical performance where metal fasteners fail. The nylon plastic construction provides inherent resistance to chemicals, fuels, and solvents while eliminating galvanic corrosion risks in multi-material assemblies. The fine UNF threads with Class 2A precision ensure superior vibration resistance in precision instruments, electrical enclosures, and machinery where headless hex drive installation enables flush mounting without protrusion. Operating across a -40° to 185°F temperature range, this RoHS 3 compliant fastener maintains dimensional stability in automotive, electronics, and industrial equipment exposed to thermal cycling, while the non-conductive properties prevent electrical shorts in sensitive applications.

Specification Summary & Compliance

Manufactured to UNF thread standards with Class 2A thread fit for precise engagement. Features 1/4"-28 fine threads, 3/4" length, and 1/8" hex drive with flat tip configuration. Compliant with RoHS 3 (2015/863/EU) environmental regulations, ensuring suitability for regulated industries and international supply chains.
