Metallics J3161F – Frequently Asked Questions
1) What size hole do I drill for the Metallics J3161F hammer drive anchor?
The J3161F is a 3/16 inch diameter anchor, so it sets in a 3/16 inch hole drilled in masonry, concrete, or block. Overall length is 1 inch, so the hole needs to be drilled deeper than the embedment you intend, clean of dust, and straight. Drive the pin home with a hammer once the body is seated flush.
2) Will the Metallics J3161F anchor hold in drywall or hollow block?
It is meant for solid base material. A 3/16 x 1 inch hammer drive anchor relies on the expanded body gripping the sides of the hole, so it works in poured concrete, solid brick, and the solid webs of block. In drywall or in the hollow cells of block it has nothing to bite and will spin or pull straight out, so use a toggle or a hollow wall anchor in those cases.
3) Is the Metallics J3161F anchor flat head or mushroom head?
Flat head. The FH in the Metallics J3161F designation means a flat countersunk-style head, which sits low against the fixture instead of standing proud like a mushroom head. That matters when you are anchoring a strap or plate that something else has to sit flat against.
4) Are these hammer drive anchors corrosion resistant enough for outdoor or damp locations?
The J3161F is zinc plated steel (St-Z). Zinc plating handles indoor and normally dry conditions well, and it will tolerate incidental moisture, but it is not stainless. For exterior exposure, wet locations, or corrosive environments, specify a stainless anchor instead of the zinc plated steel version.
5) Can hammer drive anchors be removed and reused once they are set?
No. A hammer drive anchor expands permanently when the pin is driven, so the J3161F is a one-time fastener. To remove one you either drill out the pin or snap the head off and patch the hole. If you need a fixture you can take down and remount, use a screw-type masonry anchor or a threaded insert instead.
6) How many anchors come in a jar of Metallics J3161F?
100 pieces per jar. That is a single jar of 3/16 x 1 inch zinc plated flat head hammer drive anchors, which is the usual way electricians buy them for box and strap mounting rather than counting out loose pieces on the truck.
