Precision Cup-Point Grub Screws

This pack supplies fifty alloy-steel grub screws with a 2.5 mm thread and a 3 mm cup-point tip. They are designed to lock pulleys, gears or similar components onto a shaft in surveillance equipment and other light-duty assemblies. The black finish adds basic corrosion resistance.

Verify Thread And Length Compatibility

Confirm that the mating hole is tapped for a 2.5 mm thread and that a 3 mm engagement depth is sufficient for the shaft diameter you are securing. The cup-point profile requires a matching clearance on the shaft surface to develop full holding power without damaging softer materials.

Compact Hardware For Tight Mechanisms

Each screw seats flush inside the component, freeing external space around camera mounts or bracket joints. The internal hex drive allows installation with a standard hex key where a screwdriver cannot reach. The fifty-piece quantity covers multiple mounting points across a typical surveillance installation.
