CONFAST SDF14112 – Frequently Asked Questions
1) What lengths does the CONFAST SDF split drive flat anchor come in?
The CONFAST SDF split drive flat anchor is a 1/4 inch diameter anchor offered in six lengths: 1-1/2, 2, 2-1/2, 3, 3-1/2 and 4 inches. Pick the length by how thick the material you are fastening is, plus the embedment you want in the concrete. All sizes come in the same zinc plated finish and the same box of 100.
2) Do I need a separate sleeve or expansion shield to install a split drive anchor?
No. A split drive anchor is a one piece drive-in fastener: you drill the hole in the concrete, set the fixture, and hammer the anchor in. The split shank compresses and springs back against the hole wall to hold. The CONFAST SDF needs no sleeve, shield, nut or washer.
3) Is the CONFAST split drive anchor removable if I have to take the fixture back off?
Treat it as permanent. Split drive anchors have no threads or head to turn, so once driven they cannot be backed out; removal usually means cutting or grinding the head flush. If the fixture has to come off later, use a threaded anchor such as a sleeve anchor or a wedge anchor instead.
4) Can I use the CONFAST zinc plated split drive anchor outdoors?
Zinc plating gives corrosion resistance suited to interior and exterior use in ordinary conditions. For constant wet exposure, coastal salt air or chemical environments, a stainless fastener is the better call.
5) What is the flat head version of the split drive anchor for?
The flat head sits flush once driven, so it suits fastening plates, straps, conduit clips, furring and similar flat fixtures against concrete where you do not want a protruding head. If you are anchoring something that needs a mushroom profile over an oversized hole, that is a different head style.
6) Will a split drive anchor hold in block or brick, or is it concrete only?
CONFAST lists the SDF for concrete and masonry substrates. In hollow block, drive it into the solid web or mortar joint rather than the hollow cell, since the anchor relies on the hole wall gripping the split shank. Soft or crumbly masonry will not develop the same hold.
7) How many anchors are in a box of CONFAST SDF?
Each box holds 100 anchors, all one size, which is why crews doing repetitive strap, clip or plate fastening buy it this way. Order one box per size you need, since lengths are not mixed within a box.
8) Why is a concrete anchor like this listed under electrical supplies?
The CONFAST SDF is a general purpose 1/4 inch concrete anchor, and electrical crews are among its heaviest users for fastening conduit straps, boxes and strut to concrete and block. It is not electrical-specific hardware; contractors, maintenance teams and general trades use the same anchor.
