DIN 16903 Form R

Home / Products / Moulding Inserts / DIN 16903 Form R

The DIN 16903 Form R is a brass mould-in threaded insert with a hexagonal body, with shoulder, with through-hole, 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 through-hole lets a screw pass completely through the insert; the hexagonal body resists rotation under tightening torque; and the shoulder sets seating depth with a flush bearing face. Brassland machines it from free-cutting brass CW614N (CuZn39Pb3) — or lead-free CW724R — to DIN 16903, as part of our moulding-insert programme.
