Description

Ideal for boats, docks and outdoor structures.
  • 【About Size & Quantity】1/2-13, Pack of 10. We recommend confirming the size details before purchase to ensure a fit.
  • 【Wide Application】These hex lock nuts withstand marine hardware assembly, industrial machinery, and high-salt coastal applications. 316 stainless steel construction resists corrosion from salt spray, chemical exposure, and harsh environments. Ideal for boat fittings, dock structures, offshore equipment, and coastal infrastructure projects requiring reliable vibration-resistant fastening.
  • 【Anti Loosening Design】The nut has a built-in nylon insert, which can effectively prevent loosening caused by machinery vibrations and vehicle engine work.These nuts feature a precision-engineered nylon insert that compresses against bolt threads during installation. This creates constant friction to resist loosening from machinery vibrations, engine operation stresses, and heavy equipment impacts.
