Nylon Insert Locknut 316 Stainless Steel

Nylon Insert Lock Nuts (often called Nyloc® Nuts) are Hex Nuts with a nylon ring at the top that grips the bolt threads to prevent loosening from vibration.

How It Works:

• The bolt threads cut into the nylon insert as the nut is tightened
• This creates prevailing torque (extra resistance)

Common Applications: 

• Marine and coastal structures (boats, docks, piers, seawalls)
• Chemical processing plants (acidic or chlorinated chemicals)
• Outdoor construction (bridges, signs, or exposed metal joints)
• Food and beverage equipment (sanitary environments)
• Pharmaceutical and medical equipment

316 Stainless Steel is an Austenitic Stainless Steel Alloy that contains Chromium (Cr), Nickel (Ni), and most importantly Molybdenum (Mo) which improves corrosion resistance, especially against chlorides (like saltwater) and acidic chemicals.
