Method for producing a steel part comprising providing a semi-finished product made of a steel comprising, by weight: 0.35%≤C≤0.60%; 0.15%≤Si≤0.5%; 0.8%≤Mn≤2.0%; 0.0003%≤B≤0.01%; 0.003%≤Mo≤1.0%; 1.0%≤Cr≤2.0%; 0.01%≤Ti≤0.04%; 0.003%≤N≤0.01%; S≤0.015%; P≤0.015%; 0.01%≤Ni≤1.0%; 0.01%≤Nb≤0.1%; optionally 0≤Al≤0.1%; 0≤V≤0.5%; and the remainder consisting of iron and unavoidable impurities. The method further including annealing this semi-finished product at a temperature strictly lower than the Ac1 temperature of the steel; cold forming the semi-finished product into a cold formed product; subjecting the cold formed product to a heat treatment comprising heating the cold formed product to a temperature greater than or equal to the Ac3 temperature of the steel; and holding the product at a holding temperature comprised between 300° C. and 400° C. for a time comprised between 15 minutes and 2 hours.

A die holder mounts a die to form heads on nails or screws. A top surface of the die includes a groove for longitudinally receiving and holding an elongate body. The die has a recess merging into the groove at one end of the groove to form a nail or screw head. The die is conical for press fit by contact with an inner surface of a bore or hole in the die holder. A top surface of the die is planar to a top surface of the die holder with a bottom surface engaging bottom part of the die holder. The bottom portion of the die has a recess or engaging with a corresponding protrusion die holder fixing an angular orientation of the groove relative to the die holder. Two opposite dies are brought together by two opposite die holders forming the head.

A multistage press for the bulk deformation of a piece of wire includes a wire feed with associated apparatus for cutting to length, and a transfer device—having grippers—for receiving a piece of wire that has been cut to length and transferring the latter to subsequent forming stages, there being arranged, on that side of the cutting-to-length apparatus opposite from the wire feed, a device for partially heating a length of wire. A method produces a formed part with a multistage press of this type.

A process of compressing a slug to have tapered ends, then reforming the slug to change the configuration to a shorter length with a larger diameter across the center of the slug. The slug is then reformed and a hole pressed there through, with the pressing of the partial hole reforming the configuration to have a near perfect radius with a hole through the slug, whereby a near prefect ball is made, and the ball has a hole there through.
