Machine Screw Anchor, Zinc Alloy Cone Lead Sleeve (Inch)
Zinc alloy cone‑type machine screw anchors with lead sleeves provide a durable, high‑performance solution for fastening into concrete, brick, block, stone, and other solid masonry materials. These anchors combine a zinc alloy expansion cone with a malleable lead sleeve, delivering strong, uniform expansion and excellent holding power even in irregular or brittle masonry substrates.
When a machine screw is tightened, the zinc cone is drawn into the lead sleeve, causing the sleeve to expand outward and grip securely within the hole. This design ensures consistent thread engagement, reliable load distribution, and long‑term resistance to vibration or loosening.
These anchors are ideal for medium‑duty applications where a reusable, removable, and adjustable machine screw connection is required. Don’t see the anchor cone sleeve you’re looking for on our website? Request a Quote or contact one of our knowledgeable staff members at 866-463-2910 today!

Zinc alloy cone lead sleeve machine screw anchors are commonly used for mounting:
Electrical boxes & conduit hardware
HVAC brackets & supports
Signs, plates & fixtures
Light‑duty machinery bases
Door & window hardware
Pipe clamps & straps
Interior & exterior mounting applications
The lead sleeve conforms easily to irregularities in drilled masonry holes, providing superior grip and making installation more forgiving than rigid anchor types. The zinc alloy cone ensures smooth expansion and prevents sleeve deformation during tightening.
Installation is straightforward:
Drill the recommended hole size.
Insert the anchor flush with the surface.
Install the machine screw to expand and lock the anchor in place.
These anchors offer strong, reusable internal threading ideal for applications where components may need to be removed or repositioned over time.
Available in multiple sizes to match machine screw threads and load requirements.
