How a Sleeve Anchor Grips

A sleeve anchor expands a full-length metal sleeve against the hole wall as the nut is tightened, spreading its grip over more surface area than a wedge clip does. That makes it more forgiving in brick and block, where a wedge anchor's concentrated expansion force can crack the base material.

Installation Tips

1.Drill the same diameter as the anchor — 3/8" hole for 3/8" anchor

2.Sleeve anchors work well in older or softer concrete where wedge anchors may not set properly

3.Can be used in brick and block — unlike wedge anchors

4.Don't overtighten — the sleeve can over-expand and crack masonry

Frequently Asked Questions

What size drill bit does a 3/8" Sleeve Anchor need?

Use a 3/8" carbide masonry bit, drilled to the full anchor length.

How much weight can a 3/8" Sleeve Anchor hold?

352 lbs tension, 770 lbs shear safe working load. Actual capacity depends on base material strength and embedment — verify against the manufacturer's ICC-ES ESR data for structural work.
