A specialized long-reach fastener assembly comprising a dual-threaded distance screw, smooth spacer sleeve, and expansion nylon plug, engineered for stress-free stand-off mounting and alignment of timber battens and window/door frames onto masonry or concrete.
Nylon Expansion Plug Substructure: Multi-zone expansion wall plug provides high pull-out resistance when anchored in concrete, solid brick, or hollow masonry blocks.
Dual-Thread Distance Adjustment: Upper and lower thread zones with an intermediate unthreaded sleeve allow precise clearance adjustment between the timber frame and wall without using shims.
Countersunk Torx Head: Precision star drive (TX) recess enables high torque transmission without cam-out, driving the head flush into timber frames.
Stress-Free Installation: Through-fixing capability permits rapid push-through assembly directly through the frame element into the drill hole.
