Cleanroom Installation Accessories
Expansion Anchor
A zinc-plated sleeve anchor that expands mechanically inside a drilled concrete hole to secure cleanroom support frames and brackets.
- Positive Mechanical Expansion
- Slotted Steel Sleeve
- Integrated Nut and Washer
- Immediate Load Transfer
Product Introduction
The expansion anchor combines a threaded steel shank, slotted cylindrical sleeve, tapered end cone, washer and hex nut. Tightening the nut draws the cone into the sleeve, forcing its segments against the drilled-hole wall to create a mechanical hold. The fixing is suited to cleanroom frames, ceiling supports and service brackets where a direct set-and-tighten installation is preferred in sound concrete.
Key Features
The supplied washer distributes seating pressure across the attached bracket.
Zinc-plated steel provides a practical finish for dry concealed interior support zones.
Mechanical setting provides an immediately secured connection without resin-curing time.
Customer Product Concerns
Support brackets require a predictable mechanical fixing that can be installed and tightened immediately in sound concrete.
Loose drilled holes allow the anchor to spin during tightening.Matched drill diameter and a cleaned hole let the sleeve engage the substrate uniformly.
Excessive torque can damage the substrate or deform a light bracket.The specified anchor size and setting torque control sleeve expansion and washer pressure.
Short embedment reduces engagement of the expansion zone.Hole depth and anchor length are selected so the full slotted sleeve seats in sound base material.
Unprotected steel can corrode in humid service spaces.Zinc-plated, hot-dip galvanized or stainless material is selected for the exposure.
Typical Applications
Cleanroom wall-frame anchorsCeiling support bracketsService channel base platesDoor-frame fixing platesConcrete-mounted utility supports
