What it is
The GRC-M12 E anchor with curled hook by Bossong is a mechanical expansion anchor in steel, designed for secure fixings in concrete substrates. Supplied complete with an E hammer-set anchor, this system is optimised for mounting fall-arrest nets and safety devices in industrial and construction settings. The M12 thread and the hook with a 22 mm diameter make it suitable for supporting medium to heavy loads, ensuring stability and strength in critical applications.
Heavy-duty fixings are steel or reinforced nylon anchors that carry high loads in concrete and solid masonry.
What it is for
Used for anchoring shelves, brackets and structures to walls, for mechanical fixing of structures and components to walls, ceilings and floors and for fall protection, as part of a fall arrest or work restraint system.
How to use it
Drill with a bit of the specified diameter to the required depth, then clean the hole with a brush and blow-out pump. Insert the anchor through the part to be fixed, hammering it in if necessary, and tighten the nut with a torque wrench to the torque specified by the manufacturer. Observe the minimum edge distances and spacings stated in the technical data sheet.
