Stainless Steel Nylon Insert Jam Lock Nuts
What are nylon insert jam lock nuts? Stainless steel nylon insert jam lock nuts are low-profile lock nuts that combine the space-saving height of a jam nut with the vibration-resistant grip of a nylon insert. Made from 18-8 and 316 stainless, they resist rust while locking in tight-clearance joints.
When you need locking in a thinner nut
A standard nylon insert nut is taller than a jam nut, which can be a problem where thread length or clearance is limited. The nylon insert jam lock nut solves that by putting a nylon collar in a thinner body, giving vibration resistance where a full-height lock nut will not fit. The trade-off is slightly less thread engagement, so use it where clearance drives the choice rather than maximum strength. Choose 18-8 for general use and 316 for coastal exposure.
Why choose nylon insert jam lock nuts
- Low profile: locking action in a thin, jam-height body.
- Vibration resistance: nylon collar grips the threads.
- Corrosion resistance: 18-8 and 316 hold up in wet and outdoor use.
- Grade options: 18-8 for general use, 316 for coastal exposure.
Common applications for nylon insert jam lock nuts
- Tight-clearance assemblies needing a lock nut
- Short thread projections
- Rod ends and adjustment points under vibration
- Marine and outdoor hardware (use 316)

Stainless Steel Nylon Insert Jam Lock Nuts FAQ
What grades do these come in?
18-8 and 316 stainless. Use 316 for coastal and saltwater exposure.
How is this different from a regular nyloc nut?
It has the same nylon locking collar but in a thinner, jam-height body for tight clearances, at the cost of slightly less thread engagement.
When should I choose a jam lock nut over a full nyloc?
Choose it where clearance or thread length is limited and a full-height lock nut will not fit, and maximum strength is not the priority.
