Description

TIMCO cill screws are purpose-made for fixing window and door cills to the base of uPVC and aluminium frames. The hardened self-drilling point cuts straight through both reinforced and unreinforced sections, so you skip the pilot holes and get on with the job.

The bugle head pulls in neat against the cill and the Phillips PH2 recess gives driver bits a firm grip. A zinc plated (BZP silver) finish adds everyday corrosion resistance for window fabrication and general trade work.

FAQs

What are cill screws used for?

They fix window and door cills to the base of the frame. The self-drilling point means one screw drives straight into uPVC or aluminium without a separate drilling step, which is why fabricators reach for them on the bench and for repairs on site.

Do cill screws drill through reinforced uPVC?

Yes. The self-drilling point is made to cut through both reinforced and unreinforced frames, so you can drive into steel-reinforced uPVC sections without pre-drilling a pilot hole.

What size cill screw do I need?

Match the length to how deep the cill and frame section are, leaving enough thread to bite firmly into the base. These TIMCO cill screws come in a 4.2mm gauge across a range of lengths, so pick the shortest one that still gives a solid hold.

What is the difference between a cill and a sill?

They are the same part. Cill is the spelling the UK window trade tends to use, while sill is the more general spelling. Both refer to the horizontal member at the bottom of a window or door frame.

Can I use these screws on aluminium frames?

Yes. The self-drilling point handles aluminium as well as uPVC, so the same screw suits both common frame types used in window and door fabrication.

Do I need to pre-drill before fixing?

No. The point drills and the thread taps as the screw drives, so no pilot hole is required. That is the main reason these screws speed up cill fixing.
