Metallics J2520F Anchors 1/4 x 2 Flat Hd Sleeve (Jar 100)

Sleeve anchors are drilled with a carbide bit matching the anchor's nominal diameter, so a 1/4 inch bit for the J2520F. Drill deeper than the anchor's embedment so dust has somewhere to go, blow the hole clean, then tap the anchor through the fixture and tighten the nut to expand the sleeve.

One hundred anchors per jar. Metallics packs the J2520F in jar form rather than a bulk box, which keeps the 1/4 x 2 sleeve anchors contained on a cart or in a gang box.

Flat head means a countersunk, flush-sitting head. Use the J2520F where the anchor head can't protrude, such as mounting a strut channel, a plate, or an enclosure flange against a flush surface. A hex or acorn head sleeve anchor sits proud and is driven with a socket; it's the pick when appearance and clearance don't matter and you want more torque on the nut.

Sleeve anchors like the 1/4 x 2 J2520F are made for masonry base materials, concrete, block, and brick. The expansion sleeve spreads load along the hole wall, which is why they tolerate the hollow and inconsistent material in block better than a wedge anchor does. In hollow block, land the anchor in the web or mortar joint where you can get full embedment.

No. A sleeve anchor works by expanding against the wall of a drilled hole in solid masonry, so it has nothing to grip in drywall and will spin or crush out. For hollow wall use a toggle or a self-drilling wall anchor; for wood, a lag screw. The 1/4 x 2 J2520F belongs in concrete, block, or brick.
