CONFAST SAF516312 – Frequently Asked Questions
1) What size hole do I drill for a CONFAST flat sleeve anchor?
Sleeve anchors are drilled at the same diameter as the anchor itself, so a 1/4 inch CONFAST SAF goes into a 1/4 inch hole, a 5/16 inch into a 5/16 inch hole, and a 3/8 inch into a 3/8 inch hole. Drill the hole deeper than the anchor length so drill dust has somewhere to go, and blow the hole clean before setting. The SAF is offered in 1/4, 5/16 and 3/8 inch diameters.
2) Which length CONFAST sleeve anchor do I need for the thickness of what I'm bolting down?
Pick the length by adding the thickness of the material you are fastening to the embedment you want in the concrete. The CONFAST SAF runs 1/4 x 1-3/8, 1/4 x 2, 1/4 x 3, 1/4 x 4, 5/16 x 3-1/2, 5/16 x 5, 3/8 x 3, 3/8 x 4, 3/8 x 5 and 3/8 x 6 inches. Short lengths like the 1/4 x 1-3/8 suit thin plate or conduit strap work; the 3/8 x 6 is the one for thick base plates, sills or timber where the anchor has to pass through a lot of material before it ever reaches concrete.
3) How many anchors come in a box of CONFAST SAF sleeve anchors?
Box count follows the size. The 1/4 inch sizes (1-3/8, 2, 3 and 4 inch) and the 5/16 x 5 come 100 per box. The 5/16 x 3-1/2 and all four 3/8 inch lengths (3, 4, 5 and 6 inch) come 50 per box. Useful when you are pricing out a job and need to know how many boxes cover the fastener count on the drawing.
4) What is the difference between a flat head sleeve anchor and a hex head one?
The CONFAST SAF uses a flat slotted head, which countersinks into a chamfered hole and sits flush once set, so nothing protrudes to catch a foot, a cart or a floor covering. A hex or acorn head sleeve anchor stands proud and is driven with a socket, which gives you more torque control but leaves a bump. Choose the flat slotted SAF where the finished surface has to stay clean, such as door thresholds, floor plates, and trim against concrete.
5) Can I use CONFAST sleeve anchors in block, brick or drywall instead of concrete?
The SAF is built as a concrete anchor and that is where its holding values come from. Hollow block cells and drywall give the expansion sleeve nothing solid to grip against, so it will spin or pull. If your base material is hollow, use a toggle or a sleeve-type hollow wall anchor instead. Solid grout-filled block is closer to concrete behavior, but solid concrete is what this anchor is made for.
6) Will zinc plated anchors hold up outdoors or in a wash-down area?
Zinc plating on the CONFAST SAF gives corrosion resistance for normal interior and protected commercial and industrial conditions. For constant wetting, chemical exposure, coastal air or a wash-down bay, zinc plate will eventually rust and stainless steel anchors are the right call. Dry warehouse floors, retail build-outs and interior structural work are what this finish suits.
7) Is a sleeve anchor or a wedge anchor better for fastening to a concrete slab?
A sleeve anchor like the CONFAST SAF expands along a longer sleeve, so it spreads load over more of the hole and is more forgiving in older or slightly weaker concrete, and it can be removed by backing the nut or screw off. A wedge anchor expands only at the tip, generally develops higher pull-out in sound structural concrete, and is effectively permanent. For heavy structural base plates, wedge; for equipment, strapping, framing and fixtures into a slab, the sleeve anchor is the usual pick.
8) Can I mix sizes across a job and keep the same anchor line?
Yes. The CONFAST SAF covers 1/4 inch in 1-3/8, 2, 3 and 4 inch lengths, 5/16 inch in 3-1/2 and 5 inch, and 3/8 inch in 3, 4, 5 and 6 inch, all in the same zinc plated flat slotted style. That lets a contractor standardize on one anchor family across conduit strapping, equipment bases and plate work rather than stocking several brands.
