M8 Hammer-Drive Gecko Anchors Dimensions

Applications & Industries for M8 Hammer-Drive Gecko Anchors

What Hammer-Drive Gecko Anchors are specified for, industry by industry. Stocked from M6 to M8.

Industries that specify Hammer-Drive Gecko Anchors

• Building services Colour-zinc bodies mount brackets to concrete soffits and walls.
• Site maintenance Two thread sizes cover most light bracket work.
• Concrete fixing A hammer sets the anchor with no spanner and no torque wrench.
• Formwork and temporary works Fast setting suits repetitive fixings in solid brick.
• Plant installation Machines and equipment held down to a concrete floor.
• Fit-out & drylining Fixings into board, block and hollow wall.

Typical applications

• checking the substrate is solid, not hollow
• selecting M6 or M8 for the bracket thread
• drilling to the anchor diameter in concrete or solid brick
• driving the anchor home with a hammer
• suspended services on threaded rod
• making a load-bearing threaded fixing in concrete or masonry

Service conditions to specify against

Marine and coastal

Available in A4 (316) stainless for chloride exposure — coastal structures, pool halls, water treatment and deck hardware, where A2 will eventually pit.

The concrete governs

Capacity is a property of the base material and the geometry — grade, edge distance, spacing and cracked or uncracked — not of the anchor alone. Work to the anchor manufacturer's ETA or ICC-ES report.

Hole preparation

Drilled diameter, depth and cleanliness are part of the specification; an uncleaned hole is the single most common cause of a failed anchor.

Where to use something else

• Do not use a drive-in anchor where the fixing must later be removed and re-set; it is not designed to be taken out.
• Not for a substrate the type is not qualified in — an expansion anchor near an edge or in hollow block will split it.
