The Fischer 077889 screw anchor 35 mm is a metal fixing element intended for reliable anchoring in a range of base materials. With a nominal length of 35 mm and designed for a 6 mm drill hole, this anchor provides mechanical expansion and a secure grip when installed to the required depth. Supplied in a box of 50 pieces, it is suitable for both single repairs and larger installation jobs where consistent holding power is needed.

Advantages

This screw anchor offers predictable expansion behaviour for steady load transfer and repeatable performance across multiple fixings. Its compact 35 mm length allows installation in thinner substrates while maintaining adequate embedment when used with the specified 6 mm drill hole and minimum hole depth. Packaged in quantities of 50, it simplifies planning and reduces the frequency of replenishment on site.

Suitable for

• Fastening fixtures and small fittings to concrete, masonry and solid brick
• General DIY repairs and renovation work
• Light to medium load applications such as shelving, brackets and cable clips

Key specifications

• Anchor length: 35 mm
• Recommended drill hole diameter: 6 mm
• Minimum drill hole depth: 45 mm
• Material type: metal expansion anchor
• Package quantity: 50 pieces

How to use

Drill a hole with a 6 mm drill bit to a depth of at least 45 mm, ensuring the hole is clean and free of dust. Insert the screw anchor into the hole until the head is flush with the substrate, then drive the matching screw to activate the expansion mechanism and achieve the specified hold. Confirm correct seating and tighten to the application's required torque without over-torquing to avoid damage to the base material.

Recommendations

For optimal results, use with screws that match the anchor's diameter and length recommendations, and choose a drill bit suitable for the base material. Clean the drilled hole before insertion and follow load tables or manufacturer guidelines for spacing and edge distances when installing multiple anchors.
