CONFAST SAFS383 – Frequently Asked Questions
1) What size hole do I drill for the CONFAST stainless flat head sleeve anchor?
Drill with a 3/8 inch carbide bit for the 3/8 inch diameter anchors. Sleeve anchors use a bit that matches the anchor diameter, so the hole size is the same as the nominal anchor size. Minimum embedment is 1-1/4 inches, so drill deeper than your embedment plus allowance for dust.
2) How thick a fixture can a 3/8 x 5 inch sleeve anchor hold down?
Up to 3-3/4 inches of fixture thickness with the 3/8 inch x 5 inch length. The fixture hole needs to be at least 1/2 inch diameter if you are installing through a fixture already in place. Shorter versions (3/8 inch x 3 inch and 3/8 inch x 4 inch) handle correspondingly thinner fixtures, since embedment must still be at least 1-1/4 inches.
3) How close to a slab edge can I set these concrete sleeve anchors?
Keep 3/8 inch anchors at least 1-7/8 inches from the edge of the concrete, and space anchors at least 3-3/4 inches apart. Going tighter than that risks cracking the substrate and losing the expansion grip the sleeve depends on.
4) Can CONFAST stainless sleeve anchors be used outdoors or in wet areas?
Yes. The anchor body is stainless steel and it carries a Wet location rating, which is why it gets specified for exterior railings, dock and pool-area fixtures, and washdown areas where a zinc-plated anchor would rust out.
5) What thread does the 3/8 inch sleeve anchor stud take?
The stud on the 3/8 inch CONFAST SAFS is 5/16 inch-18. That trips people up: the anchor is named for its 3/8 inch drill diameter, but the threaded portion you put a nut on is 5/16 inch-18, so bring 5/16 inch-18 stainless nuts and washers rather than 3/8 inch hardware.
6) What is the load capacity of the 3/8 inch CONFAST stainless sleeve anchor?
Published ultimate values for the 3/8 inch anchor are 1,406 lbs pull-out and 3,082 lbs shear. Those are ultimate test values, not working loads, so apply your own safety factor and confirm the concrete strength on the job matches your design assumption.
7) Why choose a flat countersunk head sleeve anchor instead of a hex head?
The flat countersunk, slotted head seats flush with the mounting surface, so nothing protrudes to catch a foot, a cart, or a finish trim piece. You drive it with a flat-blade screwdriver rather than a wrench. If you need maximum torque and do not care about a raised head, a hex or acorn head sleeve anchor is the better pick.
8) What sizes and box quantities do CONFAST stainless flat head sleeve anchors come in?
Five sizes: 1/4 inch x 3 inch and 5/16 inch x 2-1/2 inch come 100 per box, and 3/8 inch x 3 inch, 3/8 inch x 4 inch and 3/8 inch x 5 inch come 50 per box. Anchors are sold by the box, not individually, which is worth knowing if you only need a handful for a service call.
9) Will a sleeve anchor work in hollow block or brick, or only solid concrete?
Sleeve anchors expand along the length of the sleeve, which lets them grip in concrete, brick and block where a wedge anchor would be limited to solid concrete. The CONFAST SAFS is specified for concrete and masonry substrates. In hollow block, set the anchor in the solid web rather than a void, and hold the stated 1-7/8 inch minimum edge distance off mortar joints and unit edges.
10) Which length do I need if I am bolting a 1/4 inch steel bracket to a concrete wall?
For thin fixtures like a 1/4 inch plate, the 3/8 inch x 3 inch works: you only need to cover the fixture thickness plus embedment, and minimum embedment is 1-1/4 inches. Save the 3/8 inch x 5 inch for thick fixtures, up to its 3-3/4 inch maximum, or where you want deeper hold in the slab.
