Metallics LCS1265SS Anchors 1/2 x 6-1/2" Hx Hd Lg Dia CS SS (Box 20)

These are stainless steel anchors, which is the material you want for exterior slabs, rooftop equipment curbs, parking structures, and washdown areas where a plain carbon steel screw anchor would rust. For dry interior work the stainless is more corrosion resistance than you need.

Twenty anchors per box, sold boxed rather than loose or bulk. For a repeating layout like strut channel runs or equipment bases, count your hole pattern against that 20 to work out how many boxes the job needs.

A concrete screw such as the LCS1265SS threads directly into a drilled hole, so there is no expansion sleeve to set and nothing to torque against the hole wall. That makes it the simpler choice for anchoring into concrete where you may want to remove the fastener later, and for work close to a slab edge where a wedge or sleeve anchor's expansion force is a concern. If your job spec calls specifically for a torque-controlled expansion anchor, a concrete screw is not a substitute for it.

It is a fastener for anchoring into concrete, catalogued by Metallics for electrical work: strut and channel supports, transformer and panel mounting feet, large conduit racks, and equipment bases bolted to a slab. The 1/2 inch diameter and 6-1/2 inch length suit thicker standoffs and heavier supports rather than light box or strap mounting.
