Metallics J2505 Anchors 1/4 X 5/8 Slv Ancr &Nt St-zn (Jar 100)

The Metallics J2505 is a 1/4 x 5/8 inch sleeve anchor supplied with the nut, in a steel zinc-plated finish. It ships as a jar of 100 pieces, so one order covers a box of repetitive fastening points rather than a single hole.

A 1/4 inch sleeve anchor is drilled with a 1/4 inch carbide masonry bit, because a sleeve anchor's expansion sleeve matches the nominal anchor diameter rather than needing an oversize hole. The J2505's 5/8 inch length is short, so drill the hole slightly deeper than the embedment so dust clears and the anchor seats flush.

That is what they are for. The J2505 is an electrical-department fastener for anchoring straps, clamps, brackets and box backs into concrete, block and brick. The 1/4 inch size suits one-hole straps and small device boxes; the 5/8 inch length is a short anchor, so it is intended for thin fixtures bolted tight to the masonry face, not for thick spacers or standoffs.

Probably not. The 5/8 inch overall length leaves very little grip range once the fixture thickness is taken up, so it suits thin plates, straps and clamp ears. If you are fastening a thicker bracket or stacking a spacer, step up to a longer 1/4 inch sleeve anchor so there is still enough embedment left in the masonry.

Steel zinc plating on the J2505 is a mild-corrosion finish, fine for dry interior masonry and sheltered areas. For continuously wet, washdown, coastal or chemically aggressive locations, specify a stainless anchor instead; plated steel will eventually rust and lose holding value in those conditions.

Sleeve anchors like the J2505 expand along the length of the sleeve, which makes them workable in hollow block and brick as well as solid concrete, and they can be removed by backing off the nut. Wedge anchors grip at the tip and are for solid concrete and heavier loads only. For strapping, brackets and light fixture mounting the sleeve anchor is the normal pick; for structural or seismic bracing, go to a wedge or screw anchor rated for the load.

No separate nut is needed. The J2505 is supplied as sleeve anchor and nut together, 100 sets to the jar. All you need on site is a 1/4 inch masonry bit, a hammer drill, and a wrench or socket to tighten the nut.

Order by Metallics part number J2505, described as a 1/4 x 5/8 sleeve anchor with nut, steel zinc. It comes one jar of 100, which is the unit a stock room shelves and reorders against, and the jar keeps loose anchors together on a parts cart.
