Metallics J3730 – Frequently Asked Questions
1) What hole size do I drill for a 3/8 inch sleeve anchor?
Sleeve anchors are drilled at the same nominal diameter as the anchor, so a 3/8 inch sleeve anchor like the Metallics J3730 goes into a 3/8 inch carbide hammer-drill hole. Drill deeper than the embedment you need so dust can fall clear, drop the anchor through the fixture, and tighten the nut to expand the sleeve.
2) Can I use the Metallics J3730 sleeve anchor in block and brick, not just poured concrete?
Sleeve anchors are the general-purpose masonry anchor for exactly that reason: the expanding sleeve spreads load over a longer length of the hole, so they work in hollow block and brick as well as solid concrete, where a wedge anchor really wants solid concrete. The J3730 gives you 3/8 inch diameter in a 3 inch length for that kind of work.
3) How many anchors come in a jar of Metallics J3730?
Fifty anchors per jar, each with its nut. Metallics packs the J3730 in a jar rather than a box, which is the handier format for a van or a gang box when you are setting strut, panel backs, or equipment feet over the course of a job.
4) Do I need to buy nuts and washers separately for these anchors?
The nut ships with the anchor, so there is nothing else to order to make the connection. Metallics describes the J3730 as a sleeve anchor and nut, fifty sets to the jar. You will still need a 3/8 inch masonry bit and a wrench or socket to tighten.
5) Is a zinc plated sleeve anchor okay for outdoor or damp locations?
The J3730 is steel with a zinc plating, which is a dry interior finish. Zinc plating gives limited corrosion protection, so for exterior walls, parking structures, pool rooms, or anywhere washed down, specify a stainless or hot-dip galvanized anchor instead of the zinc plated steel version.
6) What are these Metallics anchors typically used for on electrical work?
Metallics catalogs the J3730 with its electrical fastener line, and a 3/8 inch sleeve anchor is the common size for hanging strut channel, panelboard and enclosure backs, conduit supports, and transformer or equipment feet off concrete and masonry walls. The 50-count jar suits an electrician stocking one size across a building.
