Fastening Devices For Bolt Centering - Form A - Hexagon Spherical Nuts With Flange JX-DIN74361-M18-ST

Name: Metric High-Strength Steel Nylon-Insert Locknuts—Class 10

Material: Carbon steel

Size: M12, M14, M18, M20, M22

A nylon insert keeps metric bolt threads from coming loose due to vibration, wear, and temperature swings. About 25% stronger than medium-strength steel locknuts, these nuts are made of high-strength, Class 10 steel. They're used in valves, pumps, suspension systems, and other high-stress parts. Combine with Class 10.9 metric bolts, which have similar strengths. All are reusable but lose holding power after each use.

Zinc-plated steel locknuts are corrosion-resistant in wet environments. Black corrosion-resistant-coated steel nuts are more corrosion-resistant in wet environments than zinc-plated steel nuts. They're also known as black luster nuts. Also known as spherical collar nuts, these nuts have a convex base that fits against a concave washer to fasten slightly uneven surfaces. They have a black-oxide finish for mild corrosion resistance in wet environments. Height includes the nut and the washer.
