Key features

  • PRECISE SPECS & FITMENT: 5/16"-18 UNC Coarse Thread | Manufactured to ASME B18.16.6 | Wrench Size: 1/2" | Total Height: 0.359" | Package: 50 Pcs
  • GENUINE 304 STAINLESS STEEL: Forged from premium 18-8 (304) Stainless Steel, providing superior rust and corrosion resistance. Unlike zinc-plated nuts, these are built for longevity in high-moisture, outdoor, and harsh industrial environments
  • ADVANCED VIBRATION SECURITY: The resilient nylon insert creates high-friction gripping power that stays locked under intense vibration. Effectively prevents hardware from loosening in high-movement equipment, ensuring long-term structural integrity and safety
  • VERSATILE SCENE MATCHING: The go-to choice for Lawn mowers, Automotive engine bays, and Deck construction. Built for medium-duty applications requiring high torque.
  • TOOL TIPS & PRECAUTIONS: Fits any standard 1/2" wrench or socket. Hand-align before using a socket wrench to prevent the nylon from galling under high-speed friction.

Free shipping included. 30-day hassle-free returns.
