Description
Overview:
Sealey Self Tapping Screws 4.2 x 13mm (BST4213) are general-purpose fasteners for sheet metal and plastics, supplied in a pack of 100. Each screw has a flanged Pozi (Pozidriv) head in a black finish, giving a wider bearing surface to help prevent pull-through on thin materials. Made to BS 4174, they provide consistent sizing and drive fit for reliable installation. These screws form their own mating thread in a suitable pilot hole, making them useful across construction fixings, equipment enclosures, automotive and bodywork tasks, and repairs on garden and site machinery housings. Manufactured from steel with a durable black coating, they are easy to fit with standard Pozi driver bits and are a practical choice for panels, trims, brackets, and ducting where a neat, low-profile head is preferred.
Key Features:
- 4.2 x 13mm self-tapping steel screws for sheet metal and plastics

- Resealable bag helps keep contents organised and protected
- Sealey part number BST4213 for straightforward identification and reordering
