The JCP Construction Products Sleeve Anchor with a Hexagon Bolt is an essential heavy-duty fastener designed for contractors and DIY enthusiasts who require secure, high-holding power in concrete and masonry surfaces. These anchors provide exceptional stability for structural and decorative attachments, though they are specifically intended for masonry applications and are not suitable for hollow brick or soft materials where expansion cannot be achieved.

These are designed for solid concrete or solid masonry. Avoid using them in fragile or hollow bricks as the expansion pressure may crack the material.
You should use a 16mm masonry drill bit to match the diameter of the anchor sleeve.
While durable, assess the environmental exposure. For highly corrosive environments, consider stainless steel alternatives if available.
The bolt can be unscrewed, but the sleeve will remain permanently expanded inside the hole.
The hole must be slightly deeper than the length of the anchor to ensure it can be fully seated.
The hole is likely too large or the sleeve is not gripping. Remove the anchor, check your drill bit size, and potentially use a chemical anchor instead.
Ensure there is no debris inside the sleeve threads. Clean the bolt and hole, then try tightening again slowly.
For proper installation, use a masonry drill bit of exactly 16mm diameter. Ensure the drilled hole is clear of dust and debris using a brush or compressed air before inserting the anchor, as loose particles can reduce holding power. Insert the anchor through your fixture until the washer sits flush against the material. Tighten the bolt with a wrench until you feel significant resistance, indicating that the sleeve has fully expanded. Always verify the masonry substrate is rated for expansion anchors before beginning work.
