XBolt Vertical Hanger, M10

What the XBolt vertical hanger is

Hobson describes the XBolt as a single unit screw type anchor for solid concrete. You drill a hole and screw the anchor in; as it goes in it taps its own thread in the concrete, which gives a mechanical interlock with the concrete. The head is a 13mm hex with a 16mm flange, and inside it is an M10 x 1.5 thread, 12mm long, that takes M10 threaded rod.

Hobson lists it for mechanical, electrical and pipe hangers, ceiling hangers, HVAC and fire sprinklers, cable tray and the suspension of mechanical services, for light to medium duty loads. It suits small anchor spacing and edge distances, is quick to install and is fully removable. It is carbon steel, zinc plated.

XBolt vertical hanger or XBolt PRO?

Hobson makes two families of screw-in hangers for concrete, and they are not interchangeable on paper. The difference is in the approvals and the load data behind them, so check what your services specification or engineer asks for.

• •XBolt vertical hanger, this page (MVXMSZIM100038): M10 rod, 38mm embedment, 6mm hole. Hobson's documents for it give working loads in non-cracked 20 and 32 MPa concrete and state no ETA, seismic or fire approval.
• •XBolt PRO vertical hangers (on our rod hanger page): M8/M10 rod at 40 and 55mm embedment and M10/M12 rod at 60mm, in zinc plated or zinc flake. Hobson's declarations of performance give them ETA Option 1, seismic C1 (C1 and C2 for the M10/M12) and a fire rating, with ETA service loads for cracked and non-cracked concrete under the conditions that page sets out.
• •Hobson lists fire sprinklers among this hanger's uses, but where the design calls for fire-rated, seismic or ETA-assessed anchors, use the XBolt PRO code the designer names: Hobson's documents give this hanger none of those approvals.

Loads Hobson publishes, and every condition on them

Hobson's data sheet gives the basic load performance below, for this hanger at 38mm embedment in non-cracked concrete of the strength shown. The shear values are at a 100mm edge distance. They are values for the anchor in the concrete, not a rating for the threaded rod, the coupling or the service hanging from it.

What the sheet does not give: values for cracked concrete, any reduction for hangers closer to an edge or to each other (it sets minimums of 40mm edge distance and 50mm spacing, but no loads at those distances), shear at less than 100mm from an edge, combined tension and shear, a minimum concrete thickness, or fire performance. So do not assume these values hold at the minimum distances. The load on each hanger, the hanger spacing, and whether the concrete may be cracked are for the services designer or an engineer to work out.

These working loads come from Hobson's factor of safety method in non-cracked concrete and are calculated differently from the XBolt PRO's ETA service loads, so the two cannot be compared directly: a higher figure here does not make this hanger the stronger choice.

Installing an XBolt vertical hanger

1. Check the base is solid concrete and that the hanger layout and load per hanger come from your services design. Keep at least 40mm from an edge and 50mm between hangers, Hobson's minimums.
2. Drill a 6mm hole, Hobson's recommended pre-drilling diameter, deep enough for the full 38mm embedment (the sheet gives no separate hole depth). Hobson lists its 6 x 110mm SDS-Plus masonry bits among the related parts.
3. Clear the dust out of the hole. Hobson lists a blow pump among the related parts for this hanger.
4. Fit the XBolt vertical hanger socket (MXSVSM10: 13mm across flats, 1/4 inch drive) to a cordless impact driver, which Hobson recommends, and drive the hanger in until the flange is home against the concrete at full embedment.
5. Screw the M10 threaded rod into the head. There is 12mm of thread in the head.

Zinc plated: for dry, enclosed positions

Hobson's finish comparison gives zinc plating about 5 microns with low corrosion resistance, recommended for indoor and non-corrosive environments, and Hobson's corrosion guide uses zinc plated only where a fixing is enclosed in a very low or low corrosivity zone. That suits services hung inside a building. For sheltered or exposed concrete, such as an open car park soffit or a coastal verandah, ask us for an alternative.

In data centres and rooms full of electronics, Hobson's zinc whisker article explains that whiskers grow from electroplated zinc, and Hobson lists its zinc flake XBolt PRO M10/M12 hanger for data centres.
