Multi-Fix Countersunk Concrete Screws 7.5 x 100mm (100/Box)

Description

Product Overview

7.5 × 100mm Multi-Fix Countersunk Concrete Screws for direct installation into solid concrete, brick, block, or masonry substrates without the use of a plug.

Manufactured from case-hardened carbon steel with a durable zinc-plated finish, they provide rapid installation, high pull-out resistance, and dependable torque control.

The countersunk head produces a neat, flush finish ideal for visible or surface-mounted fittings, while the serrated single-thread design ensures fast cutting action and secure anchorage even in dense substrates.

7.5 × 100mm sizing is suited to fixing heavy frames, lintels, and roof plates to solid masonry.

Features & Benefits

Material composition: Case-hardened carbon steel delivers superior torsional strength and thread retention under load.
Drive type: Pozi recess ensures precise torque transfer and reduced cam-out under sustained drive.
Head design: Countersunk form provides a flush, professional finish against timber or metal components.
Thread form: Serrated single-thread profile enables rapid cutting and high mechanical interlock in masonry.
Corrosion resistance: Zinc-plated coating to ISO 2081 provides reliable protection in dry interior environments.
Nominal size: 7.5 × 100mm.
Box quantity: Supplied in a box of 100 for consistent trade supply and efficient multi-project use.

Applications

Heavy frames: Secure fixing for door and window frames to masonry.
Lintels: Reliable anchorage for structural steel or timber lintels.
Roof plates: Strong connection between timber and brick substrates.

Installation Guidance

Pilot holes: Drill 6mm pilot holes using an SDS or masonry bit to a minimum of 10mm beyond embedment depth.
Drive selection: Use a Pozi No.3 bit for controlled torque application and stable recess engagement.
Insertion method: Drive at moderate speed without hammer action to maintain thread integrity.
Finishing: Tighten until the head seats flush; avoid overtightening to prevent substrate cracking.

Compliance & Performance

Manufacture standard: Produced to EN 14592 for mechanical fasteners and tested in accordance with ETA performance protocols.
Mechanical strength: Case-hardened for enhanced torsional capacity and consistent pull-out performance in solid materials.
Surface finish: Zinc electroplated to ISO 2081 for internal corrosion protection.
Safety guidance: Always wear eye and hearing protection when drilling or fixing.
Important note: Suitable only for non-cracked, sound masonry and concrete. Not designed for friable substrates or load-bearing structural anchorage.
