AIMS Industrial stocks countersunk sleeve anchors in zinc-plated steel and stainless steel for internal and external structural and fitout applications.\u003c\/p\u003e\u003ch3\u003eHow Sleeve Anchors Work\u003c\/h3\u003e\u003cp\u003eA sleeve anchor is a mechanically expanding concrete anchor — as the nut is tightened on the threaded bolt section, the slotted expansion sleeve is drawn up over the conical mandrel at the base, expanding outward against the walls of the drilled hole. This creates a load-bearing mechanical interlock with the base material that is both reliable and removable. Unlike wedge anchors (which are essentially permanent), sleeve anchors can be removed by backing off the nut, making them suitable for temporary and adjustable fixtures.\u003c\/p\u003e\u003ch3\u003eCountersunk Head Advantage\u003c\/h3\u003e\u003cp\u003eThe countersunk head is specified when a projecting anchor head would interfere with the fixed component, create a trip hazard, or where appearance demands a flush surface. Typical applications include fixing structural angle and channel to concrete floors and walls where the face of the fixed section must sit flat, floor plates and base brackets where a bolt head below the mating surface would prevent proper seating, and surface-mounted hardware where aesthetic finish is required.\u003c\/p\u003e\u003ch3\u003eSizing\u003c\/h3\u003e\u003cp\u003eCountersunk sleeve anchors are specified by bolt diameter and length — M6, M8, M10, M12 and M16 being the most common metric sizes, with lengths to suit different base material embedment requirements.
