## Long description

Frame anchor with screw UN KRP 8×140KP — 8.0×140 mm is designed for reliable fixing of window and door frames, stair stringers and other light structural elements. The fastener combines a corrosion-resistant metal screw with an expanding plastic sleeve, enabling secure anchoring in concrete, solid brick and specified hollow masonry. The head combines a hexagon exterior for wrench use with an internal Torx drive to improve torque transfer and reduce cam-out during power-tool installation.
Advantages
The combined-sleeve design ensures controlled expansion and a stable load-bearing connection in common base materials. Hexagon head plus Torx drive allows both manual tightening with a wrench and efficient use of electric screwdrivers or impact drivers, reducing installation time. The metal screw provides shear and tensile strength while the sleeve compensates for irregularities in drilled holes, improving repeatability of anchoring performance.
Suitable for
Fixing window and door frames to concrete and masonry
Anchoring stair stringers and light structural members
Mounting supports, brackets and hardware to solid brick and concrete
Applications in hollow masonry where sleeve anchors are specified
Key specifications
Nominal thread diameter: 8.0 mm
Anchor length: 140 mm
Drive type: hexagon exterior with Torx internal drive
Components: metal screw with expanding plastic sleeve
Suitable base materials: concrete, solid brick, specified hollow masonry
How to use
Drill a hole of the specified diameter to the required depth in the substrate, remove dust and position the expanding sleeve into the hole. Insert the screw through the fixture and engage the Torx drive or place a wrench on the hex head; tighten until the sleeve expands and the fixture is held flush against the base material. Do not over-torque; follow base material load guidance to achieve required pull-out and shear performance.
Usage recommendations
For reliable results, select drill bit diameter and embedment depth according to substrate and load requirements, use appropriate PPE, and verify torque settings on power tools. Avoid use in crumbling or heavily cracked masonry without reinforcement or alternative fixing methods.
