Metallics JSEA516 – Frequently Asked Questions
1) What size anchor is the Metallics JSEA516 and how many come in a jar?
The JSEA516 is a 5/16 inch single expansion anchor made of zinc alloy, packed 50 to a jar. Order quantity math is per jar, so one jar covers 50 anchor points.
2) Does the JSEA516 anchor come with the bolt?
No. The 5/16 inch single expansion anchor is the shell only, 50 per jar. You supply the 5/16 inch machine bolt, cap screw, or threaded rod and any washers to suit your fixture thickness.
3) What is a single expansion anchor used for in electrical work?
A single expansion anchor is a machine-bolt anchor set into a drilled hole in concrete, brick, or block. You drill the hole, drop the anchor in, then drive a 5/16 inch bolt or threaded rod into it; the shell expands against the hole to grip. On the electrical side that means mounting strut, panel backs, junction boxes, and conduit straps to masonry. The JSEA516 is sized for 5/16 inch bolt stock.
4) Single expansion or double expansion anchor, which do I need?
Single expansion anchors like the JSEA516 expand along one section of the shell and are intended for solid, high-strength base material such as poured concrete. Double expansion anchors expand along the full length and are the better choice in softer or lower-strength masonry like block and brick, where a single expansion can spin out. Match to the base material, not the bolt size.
5) Can I use these anchors in drywall or hollow block cells?
No. Expansion anchors like the JSEA516 need solid base material to press against, so they are for concrete and solid masonry. In drywall use a toggle or self-drilling drywall anchor; in the hollow cells of block, use a toggle bolt or epoxy with a screen tube.
6) Will a zinc alloy expansion anchor hold up outdoors or in a damp vault?
Zinc alloy gives the JSEA516 reasonable corrosion resistance for interior and sheltered work, and it will not rust-stain the way plain steel does. For continuously wet, exterior-exposed, or chemically aggressive locations, stainless anchor hardware is the usual call instead.
