About this thread insert
This is a thread insert in 1215 Carbon Steel, supplied yellow zinc plated, with an M12 thread. Every dimension is stated against the standard named above; where a tolerance class matters to your design, ask us and we will confirm it in writing before you order.
A thread insert repairs a stripped thread or reinforces a thread in a softer parent material, so a steel fastener can be used again and again in aluminium, plastic or castings. Used on castings, moulds, aluminium housings and any assembly that is dismantled often enough for the original thread to wear out.
A carbon steel, the default material for structural fastening. Anything grade 8.8 and up needs a coating — zinc, black oxide or Dacromet — or it will rust.
A zinc-based coating: zinc corrodes preferentially to protect the steel underneath. Thickness decides salt-spray life — a few µm indoors, tens of µm outdoors.
There is no minimum order and no free-shipping threshold: buy one piece or a full container. Your order total is confirmed in the cart, before payment.
