**Nylon Insert Stop Nuts, Light Hex, Thin Pattern Properties**
Description	A hex nut with a nylon filled collar at its back end. When a screw or bolt reaches the collar, the threads and nylon form a tight frictional fit, restricting movement between the nut and bolt or screw when subjected to vibration. The nylon insert comes in various colors.
Applications & Advantages	Thinner than a standard pattern nylon insert lock nut these allow for applications where an insufficient number of projecting threads are present to use a standard nylon insert nut. Designed for use with like-material screws and bolts. They are able to be reused more times than a two-way reversible lock nut. Steel nylon insert stop nuts are less expensive than grade-C automation lock nuts. However, nylon will begin to deteriorate at temperatures from 150*#176;-350°F.
Material	Steel	Stainless
#4 thru 5/8: AISI 1008 - 1010 or equivalent 3/4 thru 1 inch: AISI C1117 or equivalent	18-8: AISI 303 or equivalent stainless 316: Type 316 stainless
Hardness	Rockwell C28 minimum	1/4 thru 5/8: Rockwell B95 - C32 3/4 thru 1-1/2: Rockwell B80 - C32
Proof Load	Thin pattern nylon insert nuts are intended for use in limited clearance applications and not for load bearing purposes. If a precise engineering standard is required, parts should be laboratory tested.
