DIN 16903 Form B

Home / Products / Moulding Inserts / DIN 16903 Form B

The DIN 16903 Form B is a brass mould-in threaded insert with a round body, without shoulder, knurled on its outside so that when it is placed in the injection mould and plastic is moulded around it, it locks into the plastic part and gives a durable metric thread; the plain bore provides a standard internal metric thread; the round body suits lighter loads and tighter spacing. Brassland machines it from free-cutting brass CW614N (CuZn39Pb3) — or lead-free CW724R — to DIN 16903, as part of our moulding-insert programme.
