TECWERK Flat countersunk pot magnet D 38.1 mm, 130 N holding force

The flat countersunk pot magnet is a compact magnetic fastening element designed for industrial fixtures and high-temperature applications.

• AlNiCo 500 for elevated temperature use
• 130 N maximum holding force
• Countersunk through hole Ø 4.8 mm
• Compact diameter 38.1 mm for tight spaces

Secure retention under heat for improved process reliability

The magnet’s core advantage is its AlNiCo 500 alloy, which maintains magnetic performance at elevated temperatures up to 450 °C, reducing the risk of demagnetisation during thermal cycles. This characteristic translates into consistent clamping and positioning where temperature exposure is routine, such as in drying ovens or during coating processes. With a holding force of 130 N, the component provides measurable retention that supports steady assembly and handling, improving throughput and reducing rework.

Reliable mechanical fixing for safe, flush mounting

A countersunk through bore enables secure screw fastening in addition to magnetic grip, allowing a combined mechanical-magnetic attachment that prevents slippage on inclined or vibrating assemblies. The Ø 4.8 mm bore accepts common fasteners and the countersink allows the screw head to sit flush, preserving a low profile and preventing interference with adjacent parts. This design is particularly useful where a permanent or semi-permanent mounting is required alongside magnetic holding.

Space-saving profile with paint-bake compatibility

With a diameter of 38.1 mm and a low height of 10.4 mm, the unit is suitable for confined assemblies where a compact footprint is essential. The magnet also tolerates a coating bake temperature of 200 °C, enabling integration into painted or lacquered components without compromising adhesive processes. The compact form factor combined with thermal robustness supports efficient layout in jigs, fixtures and manufacturing aids, contributing to cleaner workflows and predictable results.

FAQ

What maximum temperature can this magnet withstand before performance is affected? The TECWERK flat countersunk pot magnet (SKU 4000832272NW) is specified for continuous use up to 450 °C, which preserves magnetic stability in high-temperature processes.

Can the magnet be fixed with a screw and still sit flush with the assembly surface? Yes. The unit features a countersunk through bore (Ø 4.8 mm) that allows a screw to be installed flush, combining magnetic holding with mechanical fastening for improved safety.

What holding capacity can be expected from this magnet in standard conditions? Under standard conditions the magnet provides a holding force of 130 N; actual performance depends on mounting, substrate material and surface flatness.

Is the magnet suitable for painted or powder-coated parts? The magnet tolerates a coating bake temperature of 200 °C, so it is compatible with many paint and lacquer processes provided the specified bake temperatures are not exceeded.
