Description
Overview:
The Sealey Self Tapping Screw pack contains 100 hardened steel screws sized 4.2 x 16mm (0.17 x 0.63 inches) with a flanged Pozidriv head and a low-glare black finish. Built to BS 4174, they are made for fast, reliable fastening into thin sheet metal and rigid plastics, forming their own mating thread for a secure hold. The integrated flange spreads the load to protect panels and reduce the need for a separate washer. These screws suit everyday assembly, repair, and maintenance on construction equipment, garden machinery, site cabinets, enclosures, guards, brackets, and trims. They can be driven with a standard Pozidriv screwdriver or a power driver with an adjustable clutch for controlled torque. Supplied in a resealable bag for tidy storage.

- 4.2 x 16mm size (0.17 x 0.63 inches) with flanged Pozidriv head for strong clamping and neat finishes

- Hardened steel body for high thread strength and long service life
- Self-tapping thread for quick installation in thin metals and plastics; pilot hole may be advisable in harder materials

- Protective black finish for a discreet look on dark panels and fittings
- 100-piece pack in a resealable bag to keep fixings organised and ready to use
- Suitable for hand or power driving at controlled speed to avoid over-tightening
- Versatile choice for repairs, retrofits, and light fabrication work
