Metallics J3730SS Anchors 3/8 X 3 Slv Ancr &Nt SS (Jar 50)

Yes, the J3730SS is the stainless steel version of the 3/8 x 3 inch sleeve anchor, which is why electrical and MRO crews reach for it on exterior strut, outdoor enclosures, and damp or washdown areas where a plain zinc anchor would bleed rust.

Sleeve anchors are drilled at the same nominal size as the anchor, so a 3/8 inch anchor like the J3730SS takes a 3/8 inch carbide bit in concrete, block, or brick. Drill deeper than the embedment you need so dust has somewhere to go, then set the sleeve through the fixture and tighten the nut to expand it.

The 3 inch overall length is split between embedment in the base material and the thickness of whatever you are fastening, so the thicker the strut channel, bracket, or standoff, the less anchor is left in the concrete. For mounting thin electrical brackets or channel to a solid wall the 3 inch length gives plenty of embedment; for thick fixtures or a shim stack, step up to a longer anchor instead of sacrificing hold.

Nuts ship with the anchors, so nothing extra is needed to set them. What you do need on hand is a 3/8 inch carbide masonry bit, a hammer drill, and a wrench or impact to draw the nut up.

A sleeve anchor like the 3/8 x 3 J3730SS expands along its full sleeve, so it works in hollow block and brick as well as solid concrete, which is where it has the edge over a wedge anchor. A wedge anchor expands at the tip only and is really a solid concrete fastener. Choose the sleeve anchor for mixed masonry on a building where you cannot be sure what is behind the face.

Fifty 3/8 x 3 stainless anchors in a jar is a shelf quantity, which suits an electrical stockroom, a service van, or a facility MRO crib where the same anchor gets used across repeat mounting work. The jar keeps the nuts with the sleeves instead of loose in a drawer.
