Expansion Sleeve – Metal Frame Connector KO, ø10×72 mm, Min. 40 mm Embedment Depth STALCO KO-10X72

The frame screw is a mounting product used in finishing construction works. The sleeve is designed to expand inside the hole during screwing, allowing very precise and stable anchoring of the element.

The STALCO KO metal frame connector is intended for use in drilled holes in solid substrates such as concrete, ceramic, and silicate bricks. It is designed for fastening window and door frames and can also be used for other elements under constant load.

STALCO KO anchors allow fast and precise installation. The product comes in several sizes, but the minimum embedment depth is 40 mm.

FEATURES

• Anchor made of carbon steel with zinc coating

• Screw head with cross recess

• Metal sleeve prevents frame deformation during tightening

• Quick and easy installation

PRODUCT MATERIAL

Sleeve and screw made of carbon steel, electroplated zinc. Fire resistance rating: Class A1. Coating thickness ≥ 5 µm.

APPLICATION

For solid building materials such as ordinary concrete C20/25.

STALCO KO expansion connectors are used for non-structural fastening of window or door frames, as well as other statically loaded construction elements. Suitable for:

• Plain, non-cracked, reinforced or unreinforced concrete C20/25 ÷ C50/60

• Solid ceramic bricks with compressive strength ≥ 15–20 N/mm²

• Solid silicate bricks with compressive strength ≥ 20 N/mm²
