## Summary description

## Long description

Niczuk TRSA expansion sleeve M8×30 mm is a metal anchoring insert supplied in a pack of 100. Designed for use with M8 bolts, the expansion sleeve creates a secure mechanical anchor when installed into pre-drilled holes in concrete, brick or solid masonry. The sleeve’s length and diameter are matched to common M8 fasteners to provide reliable grip for light-to-medium load fixings, supporting installation of fixtures, structural or non-structural elements and general fastening tasks.
Advantages
The TRSA expansion sleeve is manufactured from metal to ensure consistent expansion and long‑term dimensional stability under normal use. Its 30 mm length and M8 internal diameter are optimized for standard through-bolt installation, providing predictable load transfer into the base material. Supplied in a pack of 100, the product is suitable for repetitive installation work and reduces the need for frequent restocking. The design yields secure anchorage in concrete, solid brick and similar masonry where a mechanical expansion anchor is required.
Suitable for
 Fixing brackets, rails and frames to concrete or solid masonry
 Mounting light-to-medium load fixtures such as cable trays, pipe clamps and signage
 Installation of structural and non-structural components where M8 bolts are used
 General construction and renovation fastening tasks requiring metal expansion anchors
Key specifications
 Sleeve material: metal (for mechanical expansion)
 Internal thread/bore size: for M8 bolt compatibility
 Sleeve length: 30 mm
 Pack quantity: 100 pieces
 Recommended base materials: concrete, solid brick, solid masonry
 Application type: mechanical expansion anchoring
How to use
Drill a hole of the correct diameter and depth in the base material according to the M8 expansion sleeve specifications. Clean the hole of dust and debris before inserting the sleeve. Place the sleeve into the hole flush with the surface, insert the M8 bolt or threaded element and tighten to the torque appropriate for the bolt and substrate; tightening causes the sleeve to expand and form a mechanical anchorage. Follow standard installation practices for hole preparation, bolt selection and torque control to ensure reliable performance.
Usage recommendations
Verify that the chosen M8 bolt length and the sleeve length are compatible with the installation thickness. Use appropriate drill bits and cleaning tools to remove dust from the hole. For load-critical or safety-related applications, consult relevant standards and calculate design loads; where necessary, perform test anchors in representative substrate to confirm performance.
