Rated 5 out of 5 by Simple What can you really say about a screw - except 'It does what is say on the box" Woodley Trade Counter - quick and efficient services. 24-Sep-2014
Rated 4 out of 5 by Nut Screws Washer & Bolts What can I say? It's shiny and countersunk, with a machine screw thread. It's 40mm long and the thread is 4mm wide. They fit an M4 threaded hole just perfectly. Even though it's called a machine screw, you can use it anywhere with a suitable and deep enough threaded hole. How's that for versatility? 25-Aug-2014
Rated 5 out of 5 by GETTING ELECTRICIANS OUT OF TR When the M3.5 or 4BA female thread strip in a mounting box, especially the old metal ones with the plastic inserts, I use a M4 tap. These M4 CSK screws with relatively small heads are ideal. Pity they are not available in 30mm lengths for shallower boxes. 25-Jan-2013
