Metallics JHW14238 – Frequently Asked Questions
1) What size hole do I drill for the Metallics JHW14238 hammer drive wedge anchor?
The JHW14238 is a 1/4 inch diameter hammer drive anchor, so it goes into a 1/4 inch hole drilled with a carbide masonry bit. Drill the hole slightly deeper than the embedment you need, blow it clean, then drive the pin flush to set the wedge.
2) Can I use a hammer drive wedge anchor in hollow block or drywall?
No. Hammer drive wedge anchors only work in solid base material, concrete being the usual one, because the wedge needs solid material to expand against. In hollow block cells, brick with voids, or drywall the pin will drive without ever setting. Use a toggle or a sleeve type anchor in hollow material instead.
3) How many Metallics JHW14238 anchors come in a jar?
Fifty pieces per jar. The pack type is a jar rather than a box, which is what electricians typically keep on the truck for repeat conduit strap and box mounting work.
4) Is the JHW14238 anchor corrosion protected for damp locations?
These are zinc plated over carbon steel, which handles interior and dry locations fine. Zinc plating is a mild protective coating, not stainless, so for exterior, wet, or corrosive environments choose a stainless anchor instead.
5) Are hammer drive anchors removable, or should I use a wedge anchor with a nut?
Hammer drive anchors are a permanent, one-way fastener. Once the pin is driven the wedge is set and the anchor is not meant to be backed out or reused. If you need to remove and reinstall the fixture, use a threaded wedge anchor with a nut and washer, or a machine screw anchor, so the fastener can be undone without destroying the anchor.
6) What is the 1/4 x 2-3/8 Metallics hammer drive anchor typically used for on an electrical job?
It is a light to medium duty concrete fastener for the repetitive hangs on an electrical rough-in: one-hole and two-hole conduit straps, device and junction box brackets, strut, small panel backs, and cable clip runs on concrete walls and decks. Drill, hold the fixture, drive the pin, move on.
7) What part number do I order for the Metallics 1/4 inch hammer drive wedge anchor jar?
Order Metallics JHW14238. That is the manufacturer part number for the 1/4 x 2-3/8 zinc plated hammer drive wedge anchor, 50 to a jar.
