Arrangement and method for controlling the condition of a stud holder (14) of a welding device (10) comprising the step of:- Providing a welding device comprising a stud holder extending along a longitudinal axis (X) and forming a recess adapted to receive a stud for its welding to a workpiece and a linear drive adapted to drive the stud holder for the welding of a stud to a workpiece;- Providing a testing unit;- Aligning the welding device and the testing unit (12);- Driving the stud holder (14) of the welding device toward the testing unit;- Measuring a parameter of the linear drive for assessing the condition of the stud holder.

A fastening element (1) for fastening a first vehicle body component (20) to a second vehicle body component (23) is provided with a base body (2) comprising a plate-shaped head part (3) with latching hooks (6) projecting in the direction of the head part (3) for latching to the first vehicle body component (20). Furthermore, the base body (2) comprises a sleeve (4) which is located centrally in the base body (2) and which comprises a first opening (8) for the receptacle of a stud (22) present on the second vehicle body component (23) and a second opening (9) for the introduction of a locking element (14). The fastening element (2) also has locking fingers (11) which project into the sleeve (4), are designed to be radially resilient and are intended for a form-fitting connection to the stud (22) that can be accommodated in the sleeve (4). The locking element (14) can be brought, by an axial movement relative to the sleeve (4) in the direction of the first opening (8), into a first locking position, in which it is held in the sleeve (4) in a form-fitting manner, whereby locking arms (16) extending axially to the longitudinal axis of the sleeve (4) in the direction of the first opening (8) are present on the locking element (14) at a distance from the locking fingers (11). The locking element (14) can be moved by a further axial movement relative to the sleeve (4) into a second locking position, in which it is held in the sleeve (4) in an interlocking manner and the locking arms (16) are in active contact with the locking fingers (11), so that the locking fingers (11) can be clamped between the stud (22) and the locking arms (16).

Fastener (100) for forming a mechanical seal with a first workpiece (108) comprising: a fastener body (104) extending along a longitudinal axis (110); a fastener head (102) extending radially at a first end (114) of the fastener body (104); and a chamfer sealing portion (106) having a chamfer sealing surface (170) arranged to engage the first workpiece (108), the chamfer sealing portion (106) extending between the fastener head (102) and the fastener body (104); wherein the chamfer sealing surface (170) is inclined with respect to the longitudinal axis (110) at an angle between 15 degrees and 30 degrees; and wherein an axial length of the chamfer sealing portion (106) in a direction along the longitudinal axis (110) is between 0.1 mm to 0.4mm.

Fastener (10) and method for manufacturing a closed end hollow fastener comprising the steps of: - providing a metal body (12) with a shank (16) comprising a first end (18) and a second end (20) and having a through hole that extends from the first end to the second end, and a radial enlargement portion forming a body head (22) at the first end of the shank; - coating the body using a rack plating system, such that the inner wall of the shank defining the through hole is completely coated from the first to the second end; - providing a sealing plug (14); - fixing the sealing plug (14) to the second end of the shank (16).

A fastening element (1) for reversible connection to a stud (11), comprises a base body (2) which forms in its interior a receptacle (10) defining a longitudinal axis for at least part of the stud (11). The fastening element (1) further comprising locking fingers (15a, 15b) which are mounted on the base and whose radially elastically designed free ends project into the receptacle (10), with a locking contour at the free end of the locking fingers (15a, 15b) for locking with a locking contour of the insertable stud (11). The stud (11) can be moved into a locking position in an axial direction with respect to the longitudinal axis through an input opening (13) arranged in the bottom (8) of the base body (2) and out of the locking position in a radial direction with respect to the longitudinal axis through an exit opening (14) in a first sidewall (6) of the base body (2). The free ends of the locking fingers (15a, 15b) run along a locking-finger axis and each having an end that is close to the exit opening (14) and an end that is close to a second sidewall (4) opposite the exit opening (14), wherein the distance between the ends of the locking fingers (15a, 15b) that are close to the exit opening (14) is smaller than the distance between the ends of the locking fingers (15a, 15b) that are close to the second sidewall (4).
