Metallics J3726F Anchors 3/8 X 2-3/4 Fh Slv Ancr St-zn (Jar 100)

Sleeve anchors are drilled at the same nominal size as the anchor, so the 3/8 x 2-3/4 inch J3726F goes into a 3/8 inch hole in concrete, block or brick. Drill the hole deeper than the embedment you need so dust can settle below the anchor, drop the unit through the fixture, and tighten until the sleeve expands against the hole wall.

The 2-3/4 inch overall length of the J3726F is split between what sits in the base material and what passes through whatever you are mounting. The expansion section has to be fully inside the concrete, so plan on a thin to moderate fixture, something like a strut channel, conduit clamp, bracket or plate up to roughly half an inch. Anything thicker and you want a longer anchor in the same 3/8 diameter.

Sleeve anchors like the 3/8 x 2-3/4 J3726F are made for solid masonry, poured concrete, solid brick and the solid webbing of block. In hollow block the sleeve can expand into the void and never develop load, and in plain drywall it has nothing to grip at all. For hollow wall work use a toggle or a hollow wall anchor rated for the panel thickness.

Flat head. The J3726F is a flat head sleeve anchor, so the head countersinks flush rather than standing proud like a hex or acorn nut version. Pick it when the mounted item has a countersunk hole or when a projecting head would interfere, and pick a hex head sleeve anchor when you want to torque it with a wrench.

The J3726F is steel with a zinc plating, which is a dry indoor or protected finish. It is fine for interior slabs, block walls, mechanical rooms and conduit or strut mounting inside a building. For exterior walls, parking structures, pool rooms, coastal sites or anywhere subject to standing water, step up to a hot dip galvanized or stainless sleeve anchor instead.

They ship 100 to a jar. That quantity suits a contractor laying out a run of strut, conduit straps or equipment brackets where you are setting the same 3/8 inch anchor dozens of times, and the jar keeps the loose units together on the cart instead of in a torn box.

Order Metallics J3726F. That covers the 3/8 x 2-3/4 inch zinc plated steel flat head sleeve anchor in the 100 count jar, and it is the number to quote if you are matching anchors already set on a job so the heads and finish stay consistent.
