Fasteners, drivers, punches, fastener systems, and methods of making fasteners, drivers, punches, and fastener systems are disclosed herein. The fasteners, drivers, punches, and fastener systems include, in one example, stabilizing ribs and corresponding recesses.

Various embodiments described herein provide a fastener system having straight walled driving surfaces that provides a reliable stick fit feature, while also improving stability of engagement between the system components. A feature of the new system is to allow stick fit engagement of existing standard straight walled drivers in the new system.

A bolt includes a head portion on which a recess is formed. The recess has a bottom surface and a sidewall extending from a periphery of the bottom surface. The sidewall has a lower end defined by the bottom surface and includes an increased diameter portion and a reduced diameter portion. The increased diameter portion has an inner diameter larger than an inner diameter of the lower end of the side wall. The reduced diameter portion has an inner diameter smaller than the inner diameter of the increased diameter portion. The reduced diameter portion is located opposite to the bottom surface across the increased diameter portion.

A method of manufacturing a drill comprises providing an elongate element defining a longitudinal direction and having, in the longitudinal direction, a front end, an intermediate section, and a rear end opposite to the front end; forming by cold forming only, at the front end, a drill tip having a cutting edge; and, forming by cold forming only, on the intermediate section, a channel extending along the longitudinal direction.

The invention relates to a method for producing a gland or a gland blank (3), the method comprising a step of producing a blank (3) having a cylindrical shaft (5) formed on a screw head (4), and a blind hole (7) being formed in the blank (3) from an upper side (11) of the screw head (4) facing away from the shaft (5) in a, in particular further, method step, the blind hole (7) extending toward the shaft (5) and forming at least one first section (13), in particular having a polygonal cross section (Q1), preferably for receiving a screw tool. The blind hole (7) is deepened, thus forming at least one second section (14), which borders the first section (13), in a subsequent method step, the second section (14) forming a preferably at least partially continuous cross section (Q2) which is in particular smaller in size than the first cross section (Q1), the shaft (5) being widened in sections, thus forming an undercut (15) at the crossover between the shaft (5) and the screw head (4), in particular by at least indirectly displacing material from at least the second section (14) of the blind hole (7), in the subsequent method step.

A method of producing shaped parts includes drawing in the wire in cycles conveying the wire; severing wire portions in cycles; gripping and feeding the wire portion into work area; shaping the wire portion in multiple stages to form a shaped part with shank and head portions; ejecting formed shaped parts in cycles; transporting the fully formed shaped parts with a pneumatic conveyor system including a transporting pipe with an insertion opening: arranging the insertion opening near an ejector system such that the finished shaped parts can be inserted into the insertion opening directly in a positionally oriented manner by the ejector system; successively feeding the finished shaped parts into the transporting pipe by the ejector system; taking up the shaped parts inserted into the transporting pipe by suction into the transporting pipe; and pneumatically transporting the shaped parts through the transporting pipe in a direction of a subsequent station.

A spatially coherent machine for manufacturing comprises, in one example, a workpiece holder configured to secure a workpiece, a toolholder with at least one axis of motion control configured to perform a subtractive machining operation on the workpiece using a machining tool, a heating element configured to perform a heating operation on the workpiece, and a forming element configured to perform a forming operation in which force is applied to the workpiece in an amount that causes plastic deformation of the workpiece material. The workpiece holder secures the workpiece during the heating, forming, and subtractive operations such that the forming and subtractive operations are performed in a spatially coherent manner.

Method for manufacturing a profiled rod from a rod-shaped metal blank including a first deformation step, in which the blank is embedded in a first die arrangement, and subsequently, the blank is axially compressed so as to radially displace blank material within the first die arrangement to form a first surface protrusion structure on the blank, and following the first deformation step, a second deformation step, in which the blank is embedded in a second die arrangement, and subsequently, the blank is axially compressed so as to radially displace blank material within the second die arrangement to form a second surface protrusion structure on the blank, wherein at least a section of the second surface protrusion structure is closer to the first end than the first surface protrusion structure is.
