fischer universal plug UX 8×50 with rim and screw, for concrete, brick and boards, pack of 25
Description
fischer Universal plug UX 8 × 50 R S/25 with rim and screw is a reliable fixing for almost any base material. Its special geometry expands in solid substrates and knots in hollow and board materials, delivering high load capacity and safe installation.
Benefits and unique features
- Universal action: expansion in solid materials, knotting in hollow and board materials.
- Inclined ribs guide the screw centrally and prevent the plug from spinning.
- Rim prevents the plug from being pushed too deep and supports through-installation.
- Serrated edges improve hold in the hole during screwdriving.
- Matched screw included for optimal performance.
Properties and applications
- Applications: pictures, lighting, finishing strips, light cabinets, curtain rails, washbasins, TV brackets, bathroom accessories.
- Base materials: concrete, solid and hollow bricks, calcium-silicate blocks, natural stone, aerated concrete, gypsum boards, hollow-core floors, chipboard.
- Installation: pre-positioned (with rim) or through-installation; correct depth and screw selection ensure top load values.
