Hollow wall anchor (molly) FISCHER 84341 — metal, 105 mm length, drill Ø 14 mm, screw length 100 mm, pack 2 pcs

The FISCHER hollow wall anchor (molly) 84341 is a metal fastener designed for secure anchoring in hollow and solid substrates such as plasterboard, gypsum fibre board, brick and concrete. With a total length of 105 mm and compatibility with a Ø14 mm drill hole, this anchor is supplied with 100 mm screws and packaged as a set of two pieces. The design allows the anchor sleeve to expand behind the substrate to create a firm hold for fixtures and fittings where traditional anchors may not provide sufficient support.

Advantages

Made from metal, this hollow wall anchor provides high shear and pull-out resistance compared with plastic alternatives, enabling reliable fixation of medium to heavy loads. The 105 mm overall length and robust sleeve construction ensure deep engagement and even distribution of load forces. Supplied with appropriately sized 100 mm screws, the fastener system is ready for installation without the need for additional screw selection. The anchor is suitable for both hollow and solid materials, offering versatility for a range of mounting tasks.

Suitable for

• Mounting shelves, cabinets and towel rails to plasterboard or gypsum fibre board
• Fixing radiators brackets, TV mounts and heavy fittings to brick or concrete where through-fixing is not possible
• Securing bathroom and kitchen fixtures where a concealed expansion anchor is required

Key specifications

• Material: metal anchor sleeve and matching metal screw
• Overall anchor length: 105 mm
• Recommended drill hole diameter: 14 mm
• Screw length supplied: 100 mm
• Pack contents: 2 anchors with screws

How to use

Drill a Ø14 mm hole through the substrate at the intended fixing point. Insert the metal anchor sleeve fully into the hole until the flange sits flush with the surface. Position the fixture and start the supplied 100 mm screw through the fixture into the anchor. Tighten the screw to expand the sleeve behind the substrate until resistance indicates the anchor has set; avoid over-tightening to prevent damage to the substrate. Verify that the fixture is secure and that the sleeve expansion provides a stable hold.

Usage recommendations

Use the hollow wall anchor in substrates of sufficient thickness to allow sleeve expansion; ensure the substrate behind the surface has the required clearance for the expanded sleeve. For safety, check load requirements and use appropriate number and spacing of anchors for the intended load. When anchoring into very hard materials such as solid concrete or dense brick, confirm drilling depth and hole cleaning before insertion to achieve correct expansion and load-bearing performance.
