Metallics JDEA516 – Frequently Asked Questions
1) What size bolt does the Metallics JDEA516 double expansion anchor take?
The JDEA516 is a 5/16 inch double expansion anchor, so it is sized for 5/16 inch machine bolts or threaded rod. Drill and set the shield in concrete, brick or block, then thread the 5/16 fastener in to expand it. The bolt itself is a separate purchase.
2) How many anchors come in a jar of Metallics JDEA516?
Fifty anchors per jar. The Metallics JDEA516 is packed as a jar of 50, which is how it ships for 5/16 inch double expansion work, so one container covers a typical run of strut, panel or equipment mounting without reordering mid-job.
3) Should I use a double expansion anchor or a single expansion anchor in block?
Double expansion is the one to reach for in soft or questionable masonry, such as hollow or lightweight block, brick and older concrete. Both halves of the shield expand against the hole wall, so the load is spread over more of the hole instead of concentrated at the bottom. A single expansion shield is fine in sound, high-strength concrete. The JDEA516 is the 5/16 inch double expansion version.
4) Can I use these 5/16 anchors to hang conduit strap, strut and panel on a concrete wall?
That is exactly what they are for. The JDEA516 is a 5/16 inch masonry expansion shield catalogued for electrical work, and it is the standard way to pick up unistrut, conduit straps, pull boxes and panel backs on concrete or block. Drill the hole for the shield, blow it clean, set it flush, then bolt the strap or channel through with 5/16 hardware.
5) Do the Metallics JDEA516 anchors include the bolts?
No. The jar contains the 5/16 inch double expansion shields only. You supply the 5/16 inch machine bolts or threaded rod, cut or sized to the thickness of whatever you are fastening plus enough thread to engage the shield fully.
6) What material are the Metallics 5/16 double expansion anchors made from?
Zinc alloy body. That matters for two reasons on an electrical or MRO job: the shield is non-ferrous so it will not rust-stain finished masonry, and it stays workable in damp interior locations. For direct exposure to weather or chemicals, a stainless or hot-dip assembly is the better call.
