PEM® Self-Clinching Fasteners

PEM^® self-clinching fasteners are inserted in a hole in the workpiece. There the self-clinching fastener displaces the material in the region of the drill-hole. This material flows by cold-forming into a recess in the shank area of the fastener. A serration or a specially-shaped head now prevents the workpiece rotating – the self-clinching fastener becomes one with the workpiece. In addition, the PEM^® self-clinching fasteners leave no damage or bulges behind on the back of the component.

Advantages:

Extremely stress-resistant even in thin sheets from 0.5 mm
No special treatment of the drill-hole needed
No reworking of the thread
Ideal also for coated surfaces
High positional accuracy

PEM® Self-Clinching Nuts
Features

Self-clinching nuts have high twist- and pull-out resistance. They are available in various different shank lengths. Self-clinching nuts are suitable for metallic materials, in some cases even for use in stainless steel panels. The range of parts also includes nuts flush on both sides, closed parts, nuts with thread-locking as well as miniature designs. There is a parallel product line for insertion in PC boards.

Available in various materials, surface designs, lengths and variations
Thread sizes: from M2 to M12

PEM® Roller Bearing Fasteners
Features

PEM® Roller Bearing Fasteners are easy to install, pre-assembled rollers. They offer design engineers a user-friendly alternative to conventional high friction slide shelves. They also eliminate the cost of expensive sliding rail assemblies.

Low profile self-clinching roller bearing enables a cost-effective tray slide method.
Easy installation and simple design for use where space is limited.
Supports loads while guiding and positioning components.
Eliminates the need for oil lubricants and loose fittings normally required with drawer slides.
Press-fit roller bearing fasteners are easily installed into pre-punched or drilled holes in sheet metal as thin as 1 mm.

PEM® Round Self-Clinching Nuts
Features

Round self-clinching nuts are suitable for twist-resistant screw connections resilient from both sides in thin-walled workpieces. The designs of type RMHB were specially designed for use in restricted installation spaces as miniature designs. Unlike self-clinching nuts, the shank is riveted. For this reason, distance from the edge is a less-important criterion.

Galvanised steel, colourless passivated
Thread sizes: M3 – M4 – M5

PEM® PreTect™ Thread Masking Plugs
Features

PEM® PreTect™ Thread Masking Plugs for improved thread protection during the painting or powder coating process.

Available for standard self-clinching nuts
Available in a wide range of thread sizes and materials
Plugs can be easily removed by the end user with a fine tool
Plugs can withstand temperatures of 250˚C

PEM® Self-Clinching Studs
Features

The self-clinching studs for through holes are flush on the head side after installation. Thus no additional flanging or welding is required. Suitable for use in metallic materials, in some cases even for use in stainless steel panels. Heavy-duty stud designs with projecting head offer even better high twist- and pull-out resistance. Special studs for use in blind holes permit concealed installation.

Available in various materials, surface designs, lengths and variations
Thread sizes: from M2.5 to M10 and also in coarse-thread

PEM® Self-Clinching High-Strength Studs
Features

Self-clinching threaded studs for extremely high torque-out and pull-through resistance.

Type: HFH, HFHS, HFHD, HFHDS
Available in various materials, lengths and variations

PEM® Studs (Threadless)
Features

In addition, threadless studs for metallic materials are available. These can be used as positioning pins or stops.

Available in various materials, lengths and variations

PEM® Self-Clinching Standoffs Closed Type
Features

Self-clinching standoffs for through holes are flush on the head side after installation. Thus no additional flanging or welding is required. Suitable for use in metallic materials, in some cases even for use in stainless steel panels. Twist-resistance is assured by the hexagon head. Special standoffs for use in blind holes permit concealed installation.

Available in various materials, lengths and variations
Thread sizes: M3 - M4 - M5 and miniature thread sizes and various through-hole options

PEM® Self-Clinching Standoffs Open Type
Features

Standoffs for press-fit flush mounting. Can be pressed into round holes, hexagon head as twist-resistance.

Available in various materials, lengths and variations
Thread sizes: M3 - M4 - M5 and miniature thread sizes and various through-hole options

PEM® Self-Clinching Captive Panel Screws
Features

Self-clinching captive panel screws are captive screws either sprung or unsprung. Great variety with various fixing and release possibilities, various support surfaces and lengths of screw.

Available in various materials, lengths and variations
Thread sizes: M3 - M4 - M5 - M6

PEM® Spacer
Features

Press-in spacers for "keyhole" mounting can be used in metallic materials. They enable components to be attached and detached quickly.

Stainless steel, various spacer lengths

PEM® SMT Nuts
Features

These self-clinching nuts are taped, and are specially designed for PC board mounting. Available with or without adhesive spot. Set by soldering both in through-contact and non-plated drill-holes. There is no risk of damage to the PC board when this procedure is used.

Material: Tinned steel
Thread sizes: M2 - M2.5 - M3 - M4 - M5

PEM® SMT Spacers
Features

These spacers are taped and are specially designed for PC board mounting. Available with or without adhesive spot. Set by soldering both in through-contact and non-plated drill-holes. There is no risk of damage to the PC board when this procedure is used.

Material: Tinned steel
Thread sizes and designs: M3 and through holes 3.6 - 4.2
