Metallics CSH3F – Frequently Asked Questions

1) What size are the Metallics CSH3F hollow wall anchors, and how many come in a jar?
The Metallics CSH3F is a 3/16 inch by 2-1/4 inch hollow wall anchor in zinc-plated blue steel, packed 100 to a jar. The 2-1/4 inch length is the overall anchor body, and the 3/16 inch is the screw/anchor diameter that sets the pilot hole size you drill.
2) Will a 3/16 inch hollow wall anchor hold an electrical box or fixture on drywall?
That is the intended use. These Metallics anchors are made for drywall and other hollow wall substrates, and the described applications include electrical fixture mounting and junction box installation, plus HVAC components on hollow wall construction. They work by expanding behind the wall face as you tighten the screw, so the load is carried by the back of the panel rather than the screw threads in the gypsum.
3) Can I use these hollow wall anchors in concrete, brick, or a solid stud?
No. The CSH3F is a hollow wall anchor, and it needs open cavity behind the wall face so the sleeve can expand and grip the back side. Drive one into concrete, block, or solid lumber and it has nothing to collapse against. For solid masonry you want a masonry-rated anchor instead, and for a stud a wood screw straight into the framing is the better fastening.
4) How do you install the Metallics CSH3F anchor?
Drill a pilot hole sized for the 3/16 inch anchor and the wall thickness, push the anchor through until its flange sits flat on the wall face, then tighten the screw so the body collapses and grips the back of the panel. Keep tightening until it seats firmly, then load-test before hanging the full weight. Mark your location first and confirm there is clear cavity behind, no stud, no pipe, no cable.
5) Does the 2-1/4 inch anchor length limit what wall thickness I can use it on?
Yes, length matters with any hollow wall anchor. At 2-1/4 inches overall, the CSH3F needs enough clear cavity depth behind the panel for the body to sit and collapse. On a single layer of drywall over a standard stud bay that is fine. Where you have a shallow cavity, furring over solid masonry, or a fire-rated double-layer assembly, measure the depth and the total panel thickness before you commit to a hundred of them.
6) Is the zinc plating on these anchors good enough for a damp or unconditioned space?
The zinc plating on the blue steel body is a corrosion-resistant coating meant to extend service life across varying environmental conditions, which covers ordinary interior work including unconditioned back-of-house and mechanical spaces. It is a plated carbon steel anchor, not stainless, so for wet exterior exposure or a corrosive chemical environment you would specify a stainless fastener instead.
7) Is a 100-count jar of these anchors practical for a maintenance truck or MRO stockroom?
That is what the packaging is for. These ship as a 100-piece jar rather than a blister card, which suits a contractor van, an electrical stockroom, or a property maintenance shop doing repeat fixture and box mounting across multi-unit residential, office, and retail buildings. One part number covers the 3/16 by 2-1/4 size across all of those openings, so you are standardizing on a single bin rather than several card packs.
