Metallics J2513F Anchors 1/4 x 1-3/8 Flat Hd Sleeve Zn (Jar 100)

Sleeve anchors are drilled to match the anchor's nominal diameter, so a 1/4 inch sleeve anchor takes a 1/4 inch carbide bit in concrete, block or brick. Drill at least as deep as the anchor so the expansion sleeve sits fully in the base material; at 1-3/8 inch overall length this anchor is short, so subtract the thickness of the strap, clip or bracket you are fastening to see how much embedment you actually get.

A sleeve anchor expands against the sides of a drilled hole, so it needs solid material to grip. In solid concrete, brick or the solid web of a block it works. Driven into drywall or the hollow cell of a block there is nothing for the sleeve to bear on, and it will spin or pull out. For those substrates use a toggle or a hollow-wall anchor rather than the 1/4 x 1-3/8 sleeve.

That is the normal use for it. A 1/4 inch sleeve anchor at 1-3/8 inch length suits light attachments such as conduit straps, strut clips, box mounting feet and small brackets on concrete, block or brick. The flat head sits close to flush against the fixture, which keeps the strap tight to the wall. For heavier loads or anything needing deeper embedment, step up to a longer anchor or a wedge anchor.

The J2513F is zinc plated, which is a dry interior or protected finish. It holds up fine in conditioned spaces, mechanical rooms and covered areas, but direct weather exposure, wet locations or coastal air will corrode plated steel. For those openings use a stainless sleeve anchor instead.

Order it as Metallics J2513F. That number covers the 1/4 x 1-3/8 inch flat head zinc sleeve anchor in the 100 piece jar; there is one configuration, so no size or finish suffix to pick.
