DIN982 A4-80 m8 Nylon Insert Lock Nut Specifications Stainless Steel 316L

Metric Super-Corrosion-Resistant 316 Stainless Steel Nylon-Insert Locknuts

Product Description:

Made from 316 stainless steel, these locknuts have excellent resistance to chemicals and salt water. The nylon insert grips the bolt to resist loosening without damaging threads. They're reusable, but their holding power lessens with each use. Metric 316 stainless steel is also known as A4 stainless steel. Nuts may be mildly magnetic.
All meet DIN 982, which are no longer active standards, but are still a common reference point for designers.
Threads are molded into the nylon insert locking the bolt into place.
Nylon Insert Lock Nuts typically have a cased metal outside formed into a hex pattern easily torqued by a wrench or socket.
A4-70 Stainless steel per ISO 3506-2.
6H thread requirement.
