10g X 40mm T17 Countersunk Screw Galvanised C3 Phillips Drive 1000 Pack

10g X 40mm T17 Countersunk Screws | Get the Job Done Right, First Time.

Need a reliable all-rounder for those general fixing jobs? These galvanised countersunk screws are designed for sinking flush and holding tight.

This 1000 pack of 10g x 40mm countersunk screws is your go-to for a range of timber and general construction applications. The Type 17 slash point means these screws will bite quickly and reduce the risk of splitting the timber, saving you time and frustration. They're driven with a standard #2 Phillips (PH2) drive, fitting most common driver bits. The countersunk head ensures a flush, clean finish, and the 40mm length provides plenty of bite for secure fastening.

Manufactured from hardened steel for durability, these screws are finished with a Galvanised Class 3 coating. This gives them decent protection against rust and corrosion, making them suitable for both indoor and protected outdoor use. The 10g gauge (approx. 4.8mm) provides a good balance between holding power and ease of driving. With 12 threads per inch, these screws provide a strong, consistent grip.

Pro Tip: When working with hardwood, pre-drilling a pilot hole is always recommended. It’ll save your driver bit and make the job a whole lot easier on yourself. A pilot hole that's slightly smaller than the screw's core diameter will ensure a tight, clean fix.
