Brass expansion sleeve Niczuk M10 x 34, model 1440010000

The Brass expansion sleeve Niczuk M10 x 34 (model 1440010000) is a threaded expanding insert designed to form a secure internal anchor in hollow or softer base materials. Made of brass for improved corrosion resistance, the sleeve expands when a threaded rod or bolt is tightened, generating radial pressure against the cavity walls to hold fixtures and components. The 34 mm body length provides engagement depth suitable for many medium-thickness installations, and the M10 internal thread accepts standard M10 rods and bolts.

Advantages

This brass expansion sleeve offers corrosion-resistant material properties that extend service life in moist or mildly corrosive environments compared with some steel alternatives. Its expanding mechanism provides reliable load transfer to cavity walls without the need for external nuts or backing plates. The component is compact and simple to install, making it practical for concealed anchoring where visible hardware is undesirable. Compatibility with M10 threaded elements ensures straightforward integration with common fasteners.

Suitable for

• Anchoring fixtures in hollow blocks and cavity walls
• Mounting brackets, light fixtures, and pipe clamps
• Applications requiring an internal expansion anchor with M10 thread
• Situations where corrosion-resistant brass is preferred over plain steel

Key specifications

• Material: brass
• Internal thread size: M10
• Body length: 34 mm
• Type: threaded expansion sleeve / internal expanding insert
• Function: radial expansion to create an internal anchor in cavity or softer materials

How to use

Drill a hole to the appropriate diameter for the sleeve in the base material, clean out debris, and insert the sleeve flush with the surface. Introduce an M10 threaded rod or bolt into the sleeve and tighten to the specified torque; as the fastener advances, the sleeve expands radially and grips the surrounding material. Ensure the installation depth allows the full 34 mm body to engage the cavity. Follow fastener manufacturer torque recommendations to achieve secure expansion without over-tightening.

Usage recommendations

Use the Brass expansion sleeve Niczuk M10 x 34 in conjunction with correctly sized M10 bolts or threaded rods and verify hole diameter and base material suitability before installation. For critical loads or safety-related fixings, confirm load ratings and, if necessary, consult structural guidelines or perform a pull-out test in the actual substrate.
