Nylon Insert Lock Nut: a Nylon Collar Crimped into a Steel Nut
A nut that will not shake loose. A nylon collar sits in a recess at the top of the nut; its hole is a little smaller than the bolt, so the bolt presses its own thread into the nylon and the nylon grips it. Sauer (US 2,450,694, 1948) chose nylon over the older fibre collar: it hardly takes up water and still locks after 50 to 100 re-uses. The collar is held as Swanstrom's patent (US 2,153,681, 1939) shows: the recess wall is pressed in and crimped over it. Size M10 is ours.

Mould a nylon washer that fits the recess, with a hole somewhat smaller than the bolt's outside thread diameter. Nylon is thermoplastic, so scrap can be moulded again.
