Professional Applications & Engineering Value
This nickel-plated brass cap nut delivers exceptional value in applications where corrosion resistance and thread protection are critical. The combination of brass material with nickel plating creates a barrier against moisture, chemicals, and environmental factors that typically degrade fastener performance. The 1/4"-28 UNF fine thread configuration provides superior clamping force distribution, making these cap nuts ideal for precision equipment, electrical enclosures, and marine applications where vibration resistance is essential. The external hex drive allows for quick installation with standard tools while the enclosed cap design prevents thread damage and contamination in demanding industrial fastening scenarios.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 2B thread fit tolerance for optimal engagement. Features UNF (Unified National Fine) thread form with right-hand direction and fine thread spacing (28 TPI). Dimensions include 7/16" width across flats, 3/8" height, and 5/32" thread depth.
