Klimas Anchor Sleeve Plug KS-12/8x80 — plastic expansion dowel for masonry and concrete, 12 mm, length 80 mm

Klimas Anchor Sleeve Plug KS-12/8x80 is a plastic expansion dowel engineered for secure fastening in masonry and concrete. With a nominal diameter of 12 mm and an overall length of 80 mm, the sleeve plug expands mechanically as a screw or bolt is driven in, creating a reliable hold for medium-duty fixtures. The product is intended for use in building and renovation tasks where anchors are needed to attach rails, brackets, cabinets and similar elements to solid substrates.

Advantages

The plastic expansion design provides consistent expansion performance in both masonry and concrete, reducing the risk of pull-out under typical loads. The 80 mm length gives adequate embedment depth for medium-thickness fixtures while the 12 mm diameter accommodates common metric fasteners for a secure fit. Made from durable plastic, the sleeve resists corrosion and is suitable for indoor and sheltered outdoor applications when combined with appropriate metal fasteners. The product is compatible with standard drills and commonly used screw and bolt sizes, simplifying installation.

Suitable for

• Fixing rails and handrails to concrete or block walls
• Mounting cabinets, shelves and brackets
• Securing lightweight structural elements and frames
• Attaching fixtures in renovation and construction projects

Key specifications

• Nominal diameter: 12 mm
• Overall length: 80 mm
• Material: plastic expansion sleeve
• Suitable base materials: masonry, concrete
• Fixing method: mechanical expansion with screw or bolt

How to use

Drill a hole in the substrate to the recommended diameter and depth for a 12 mm sleeve and 80 mm embedment. Clean the hole of dust and debris before inserting the plastic sleeve flush with the surface. Place the fixture or bracket and align the fastener, then drive the screw or bolt into the sleeve so that the plug expands and anchors in the base material. Ensure the fastener length allows full engagement without bottoming out or leaving insufficient thread length for secure expansion.

Usage recommendations

Use appropriate screw or bolt dimensions rated for the intended load and environment; in outdoor or humid conditions select corrosion-resistant metal fasteners. Match drill bit diameter and hole depth to the sleeve size, and follow local building codes and load tables for spacing and load-bearing limits.
