Machine Screw Anchors
Machine screw anchors provide a durable, reusable, and secure anchoring solution for brick, block, concrete, stone, and other solid masonry materials. Designed to accept machine screws or bolts, these anchors feature an internally threaded body that expands tightly when a screw is inserted, creating a strong, vibration‑resistant hold.
Their versatile expansion design makes machine screw anchors ideal for medium‑duty fastening, especially in applications requiring hardware removal or replacement without damaging the base material. These anchors are commonly used where precision alignment, repeat installations, or robust thread engagement are essential.
Typically made from zinc alloy, lead alloy, or other formable materials, machine screw anchors offer excellent conformity to irregular masonry holes while maintaining consistent holding power.

Machine screw anchors are commonly used for:
Electrical boxes & conduit hardware
Signage, brackets & fixtures
HVAC supports & mounting plates
Door frames & window hardware
Shelving & utility hardware
Light machinery & equipment bases
Plumbing hardware & pipe straps
Installation is simple: drill the proper hole, tap in the anchor flush with the surface, and install the appropriate machine screw to expand the anchor. This expansion creates secure internal threads inside solid masonry, allowing repeated tightening and removal without degrading holding strength.
Machine screw anchors are an excellent choice for commercial construction, facility maintenance, mechanical installation, and interior mounting in masonry substrates.
Available in multiple thread sizes, lengths, and material types to match machine screw specifications and load requirements.
