Description

Baypole screws are what fabricators reach for when they're joining PVCu bay window poles and sections. This TIMCO screw has a low-profile wafer flange head, a Phillips PH2 recess and a self-drilling point. It cuts its own hole through the steel reinforcement inside the frame, so there's no pilot hole to mess about with. The 4.8mm carbon steel shank is fully threaded with a V-flute pattern, so it grips hard along its full length and pulls up a firm, flush clamp. Handy on the bench for bay window assembly, and it does the job across general window and door fabrication too.

Key Features & Benefits

  • Self-drilling point cuts its own hole and drills steel up to 4.0mm thick. No pre-drilling needed.
  • Wafer flange head sits low and spreads the clamping load over a wide area for a neat, secure joint.
  • Phillips PH2 recess drives quick and stays put on the bit.
  • Fully threaded V-flute shank bites the full length of the screw.
  • 4.8mm carbon steel with a zinc (silver) finish for everyday corrosion resistance. Corrosion Rating 2.
  • Made for PVCu bay window poles and sections, and works across window and door fabrication.
  • Fire Classification A1. Tested to BS EN ISO 9227 and made to BS 7412, BPF and GGF guidelines.

Usage / Application

  • Joining PVCu bay window poles and sections during bay assembly.
  • uPVC window and door fabrication on the bench.
  • Fixing through steel reinforcement up to 4.0mm thick inside the frame.
  • General trade fabrication where a low-profile head and a self-drilling point save time.

FAQs

What is a baypole screw?

It's a self-drilling fabrication screw made for joining PVCu bay window poles and sections. The wafer flange head keeps the joint low and flush, and the self-drilling point means it bites straight into the steel reinforcement inside the frame.

Do I need to pre-drill before fitting these?

No. The self-drilling point cuts its own hole through steel up to 4.0mm thick, so you can drive straight in. That saves a step on the bench and keeps your assembly moving.

Which window sections do they suit?

They're aimed at PVCu bay window poles and sections, but fabricators use them right across uPVC window and door work. Anywhere you're fixing into steel reinforcement up to 4.0mm, they'll do the job.

How thick a steel will they drill through?

Up to 4.0mm. That covers the galvanised steel reinforcement you'll find inside most uPVC frames and bay poles.

What's the finish, and how well does it hold up?

They're carbon steel with a zinc (silver) finish and a Corrosion Rating of 2. That gives sensible corrosion resistance for internal fabrication work.

Are they approved to any standards?

Yes. They're made to BS 7412 along with BPF and GGF guidelines, and tested to BS EN ISO 9227. Fire Classification is A1.
