Concrete Anchor Installation Instructions
- Drill a hole in the base material using a carbide drill bit (complying with ANSI B212.15) with the same diameter as the nominal diameter of the anchor to be installed. Drill the hole to the specified minimum hole depth overdrill (see table below) to allow the thread tapping dust to settle, and blow it clean using compressed air. (Overhead installations need not be blown clean.) Alternatively, drill the hole deep enough to accommodate embedment depth and the dust from drilling and tapping.
- Insert the anchor through the fixture and into the hole.
- Tighten the anchor into the base material until the hex-washer head contacts the fixture.
Caution
- Holes in steel fixtures to be mounted should match the diameter specified in the table below if steel is thicker than 12 gauge.
- Use each Torpedo Bolt one time only — installing the anchor multiple times may result in excessive thread wear and reduce load capacity.
- Do not use impact wrenches to install into hollow CMU.
- Oversized holes in base material will reduce or eliminate the mechanical interlock of the threads with the base material and reduce the anchor’s load capacity.
- Installation of concrete screw generally is influenced by many factors such as but not limited to, concrete compressive strength, type of aggregate, installation location, installation direction and tools used for installation.
Frequently Asked Questions
What are Torpedo Bolts?
8 in x 1/2 in self-cutting screw anchors for concrete (cracked or uncracked) and asphalt. They are made by Roadly and recommended for rubber curbs and signs.
How do I install them?
Drill a hole the same diameter as the anchor with an ANSI carbide bit, deep enough for the embedment plus dust, and blow it clean. Then drive the anchor through the fixture until the hex washer head is tight.
Can I reuse them?
No. Use each Torpedo Bolt one time only; reinstalling wears the threads and lowers holding power.
What do I use them for?
Rubber parking curbs, flexible sign posts and sign base plates.
