About this anchor
This is a anchor in Plastic, supplied grey, with an M4 thread and a 20 mm length. Every dimension is stated against the standard named above; where a tolerance class matters to your design, ask us and we will confirm it in writing before you order.
An anchor transfers load from a fixture into masonry or concrete, expanding or bonding against the drilled hole so the fixing develops its strength from the base material. Used for racking, handrails, façades, plant and machinery bases, and any fixing into brick, block or concrete that has to take a working load.
An engineering polymer, used for light-duty, insulating or non-marking parts rather than structural joints.
M4 is a metric thread with an 4 mm nominal diameter and a coarse pitch of 0.7 mm (ISO 261). A standard hex head takes a 7 mm spanner across the flats.
Sold by the piece, so one is a valid order. Stock lines leave our warehouse within 24–48 hours of cleared payment, and freight is calculated at checkout from the packed weight and the destination.
