Threaded Rod In Concrete

The appropriate fastener specification will depend on the application.

Threaded rod in concrete.

All thread rod anchor bolts are commonly specified using the anchor bolt specification f1554 in grades 36 55 and 105. The astm a307 specification covers carbon steel bolts and studs ranging from 1 4 through 4 diameter. They are embedded in concrete and provide pull out resistance with their fully threaded bodies along with the help of a nut or nut and plate combination. They include a threaded rod anchor for supporting a single threaded rod.

Set is a high strength non shrink epoxy based adhesive formulated for anchoring and doweling threaded rod and rebar. Technically all thread rod made from a36 steel should be ordered to a fastener specification such as a307 grade a a307 grade b f1554 grade 36 or sae j429 grade 2. Flush mount expansion anchor for concrete applications rod size. All thread rods are often used as anchor bolts.

Drop in anchors are also available in coil threaded versions for 1 2 in. The anchor is set by driving the expansion plug towards the bottom of the anchor using the setting tool. Also known as rod anchors they re often used with threaded rod to hang pipe and wiring. This is your everyday run of the mill bolt specification often manufactured using a36 round bar.

Use a threaded rod hanger from grainger to suspend threaded rod from concrete slabs and wood or steel beams in order to hang pipes cable tray and hvac equipment. Steel is strong and durable but less corrosion resistant than stainless steel. Suspension beams for threaded rod mount these beams across parallel roof joists to hang threaded rod and route pipe duct and other overhead systems in areas where there s no anchoring point. Shop grainger for the type of threaded rod hanger in the size and material you need.

Threaded rod hangers are high strength screw anchors. To improve its resistance to corrosion it may receive additional finishes and coatings. Beams are shaped to fit beneath corrugated roofing. Drop in concrete anchors are internally threaded expansion anchors used with machine screws and bolts.

Threaded rod is often used along with a nut and or square plate washer when embedded in concrete to achieve required pull out values. However some companies stock all thread rod manufactured from a36 steel and can certify it as such upon.
