Key Features & Benefits at a Glance
- Vibration-resistant locking: Nylon patch thread locker prevents loosening under dynamic loads, maintaining assembly integrity from -70° to 250°F.
- High-strength durability: 70,000 psi tensile strength and Rockwell B55 hardness ensure reliable performance in demanding industrial environments.
- Precision shoulder alignment: Smooth 1/4" diameter shoulder with tight length tolerance (±0.002") enables accurate component positioning.
- Corrosion-resistant construction: 18-8 stainless steel material provides excellent resistance to rust and chemical exposure.
- Secure fine-thread engagement: 10-32 UNF Class 2A threads offer superior fastening in thin materials and vibration-prone applications.
- Easy installation and removal: Standard socket head design allows for efficient assembly with common hex tools.
- Regulatory compliance assurance: Meets RoHS 3 and REACH standards for use in regulated industries worldwide.
Professional Applications & Engineering Value
This precision 10-32 UNF shoulder screw with nylon patch thread locker solves critical alignment and vibration challenges in industrial machinery. The 18-8 stainless steel construction maintains dimensional stability while resisting corrosion in harsh environments. The precisely machined shoulder with 1/4" diameter and 7/16" length provides accurate locating surfaces for rotating components, bearings, and linkages. The fine UNF threads with Class 2A fit ensure secure fastening in thin-section materials where standard threads might strip. The integrated thread locking feature eliminates the need for separate locking compounds, reducing assembly time while maintaining joint integrity under continuous vibration. Ideal for precision equipment, automotive assemblies, and electronic enclosures requiring reliable, maintenance-free fastening solutions.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 2A thread fit and shoulder diameter tolerance of -0.001" to 0". Features UNF fine threads (10-32) with 1/4" thread length and right-hand direction. The shoulder maintains 1/4" diameter with 7/16" length and tight tolerance control. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations for environmental safety and restricted substances.
