Screw hook & wall plug kit FISCHER 94621 UX 8 x 50 nylon anchors, screws 5.5 x 84, 4 pcs

The Fischer 94621 screw anchor and wall plug kit contains four UX universal nylon plugs with round hooks intended for fixing lights, pictures and other suspended objects. Each plug is 8 mm in diameter and 50 mm long, and the set includes screws sized 5.5 x 84 mm. The UX universal fixing is designed to hold in a wide range of base materials by either expanding in solid substrates or knotting in hollow and board materials; an integrated rim prevents the plug slipping into the drill hole during insertion.

Advantages

The universal operating principle of the UX plug (expanding or knotting) makes it suitable for solid, hollow and board building materials, which is useful when the base material is unknown. Angled connection ridges on the plug guide the screw accurately while serrated anti-rotation locks minimise turning in the drill hole, increasing installation safety. The kit includes round hooks matched to the plugs, so you have the correct hook available and do not need to source them separately.

Suitable for

• Hanging pictures and mirrors
• Fixing lighting fixtures and pendant lamps
• Mounting towel rails and bathroom accessories
• Securing small shelves and TV consoles

When it may not be suitable

The UX 8 x 50 kit is not intended for heavy structural loads or large suspended loads beyond the combined capacities of the plug and the included screw; for heavy-duty anchors consult load tables or use purpose-designed heavy anchors. It is also not suitable where the screw length or diameter requirements differ substantially from the included screw (5.5 x 84 mm) or where non-nylon chemical resistance is required.

Key specifications

• Plug material: Nylon
• Plug type: Universal UX (expanding/knotting)
• Plug diameter: 8 mm
• Plug length: 50 mm
• Included screws: 5.5 x 84 mm (suitable for wood/chipboard and stud screws)
• Quantity per pack: 4 sets (plug with round hook)
• Drill hole diameter: 8 mm

How to use

Drill a hole with an 8 mm drill bit to the required depth, ensuring the edge distance is at least one plug length. Insert the UX plug with rim flush to the fixture so the rim prevents the plug slipping into the hole. Use the included screw (5.5 x 84 mm) or an equivalent screw; when tightened the plug will expand in solid substrates or knot in hollow and board materials to provide secure anchoring. For board materials ensure the threadless part of the screw is not longer than the fixture.

What to consider before purchase

• Confirm base material (concrete, brick, plasterboard, aerated concrete, chipboard, etc.) and suitability of a universal UX plug
• Ensure the included screw length (5.5 x 84 mm) matches your fixture thickness and required embedment
• Check required drill diameter (8 mm) and available drill depth
• For heavy loads, consult load tables or choose a heavy-duty anchor

Usage recommendations

Use the UX 8 x 50 with the included round hook for medium-duty wall fixings such as lights, pictures and towel rails; maintain recommended edge distances and use the specified 8 mm drill bit for reliable performance.
