Description
The Chem-Set 10F18MXRLZ is a number 10 flat head Phillips tapping screw built for fast, self-tapping installs into sheet metal, plastic housings, and light hardware assemblies. The 18mm length and 3/16 inch head give it enough bite for panel and bracket work without oversizing the pilot hole, and the zinc plating holds up against everyday shop humidity, handling, and light outdoor exposure without the added cost of stainless steel.
Where the Chem-Set Tapping Screw Fits
This screw is sized for production and repair work where a separate nut or insert would slow the job down. Typical uses include:
- Securing sheet metal brackets, clips, and enclosure panels where the screw cuts its own mating thread
- Light assembly on hardware, fixtures, and fabricated metal components in cabinet, signage, and fixture shops
- Field service and repair kits that need a compact, corrosion-resistant fastener on hand for quick fixes
- Retrofitting an existing hole where a slightly oversized, self-tapping screw restores a solid grip

Pilot hole size should match the base material thickness and hardness. Thinner sheet metal generally needs a smaller pilot than heavier gauge stock, and softer plastics may need none at all if the screw is self-tapping into a molded boss. Drive the Chem-Set screw with a properly sized Phillips bit at a controlled speed to avoid stripping the head or camming out before the threads fully seat. Running the screw in and backing it out once on a test piece helps confirm hole size before committing to a full production run. For related hardware, browse Chemical Concepts hardware.
