Description

These are TIMCO's countersunk concrete screws with a TX flat head and yellow finish. They are a fast, tidy way to fix into concrete, brick, stone, block and timber without a separate plug or anchor: the hardened thread cuts its own path into the masonry as it drives. The flat countersunk head sits flush, and the TX drive holds the bit steady under load. A light-duty through-fixing for brackets, battens, frames and fittings.

Key Features & Benefits

  • No plug or anchor needed. One through-fixing does the work of traditional nylon frame and hammer fixings, so you save time on site.
  • Flat countersunk head with five locking ribs. It sits flush and grips the fixture to resist pull-through and loosening.
  • TX Drive recess (TX30). Less cam-out and driver wear for fast, controlled driving. An S2 TX30 bit is included.
  • Serrated V-thread with Hi-Low start. The Hi-Low thread on the first 30mm aids insertion and cuts the torque needed for a good bite in any masonry.
  • Non-expansion design. Fix closer to edges without damaging the substrate.
  • Carbon steel, Zinc & Yellow passivated (ZYP). Added corrosion resistance for interior, clean and dry environments (Corrosion Rating 1).
  • BS 7671:2018 (18th Edition) approved. An all-steel, non-flammable fixing suitable for supporting wiring systems.
  • Multi-substrate. Concrete, solid and perforated brick, block, natural stone and wood.

Usage / Application

The TIMCO Multi-Fix Concrete Screw earns its keep across most masonry jobs:

  • Fitting window and door frames directly through the frame into masonry.
  • General fixing into concrete, brick, block and stone: battens, brackets, rails, fence posts and timber to masonry.
  • Electrical wiring support. The BS 7671:2018 approval makes it suitable as an all-steel, non-flammable fixing for cables, trunking, conduit and containment.

FAQs

Do you need a plug or anchor with concrete screws?

No wall plug or anchor. The TIMCO Multi-Fix Concrete Screw is a through-fixing that drives straight into the masonry. Drill the hole, drive the screw, and it cuts its own thread for an immediate hold.

What size hole do I drill for these concrete screws?

Go with a 6.0mm diameter hole for the 7.5mm Multi-Fix screw, drilled deep enough to give at least 35mm minimum embedment into the base material. In harder materials you may need a 6.5mm hole.

Can they be used for electrical or wiring support?

Yes. They're approved to BS 7671:2018 (18th Edition) as an all-steel, non-flammable fixing, so they're fine for supporting wiring systems such as cables, conduit, trunking and containment.

What substrates can I fix into?

Concrete, solid and perforated brick, block, natural stone and wood. One fixing covers most masonry tasks.

What bit do the screws use?

A TX30 (Torx) drive. There's an S2 TX30 driver bit in the box, so you're ready to fix straight away.

Are these screws suitable for outdoor use?

They carry Corrosion Rating 1 (zinc & yellow passivated) and are meant for clean, dry, low-humidity interior conditions. For anything permanently wet or exposed outdoors, pick a higher corrosion-rated fixing.

Available in a range of lengths (7.5mm diameter, roughly 40mm to 200mm), supplied in a box of 100 with a TX30 bit included. A fast, reliable masonry fixing that window fitters, builders and electricians rely on.
