Product Description

A sleeve anchor is a pre-assembled mechanical expansion anchor used to securely fasten objects to solid base materials such as concrete and masonry. It consists of an inner bolt and an outer expansion sleeve. When the nut is tightened, the bolt is pulled outward, forcing the expansion sleeve to expand outward and grip the walls of the hole tightly like claws, providing strong frictional locking force.

  • Stainless steel: Copper nut, inlaid copper nut, knurled copper nut, embedded copper nut, injection copper nut
  • Round nut, ring nut, butterfly nut
  • DISC-LOCK lock nut: Two-part design with staggered CAMs for vibration resistance

Material Specifications
Aluminum Excellent thermal/electrical conductivity but naturally soft. May produce gelatinous buildup during processing.
Titanium EDM machining recommended. Requires deionized water to control heat during processing.
Steel Very strong metal. Wire cutting machines often preferred for complex features. Requires heat management.
Brass High tensile strength, easy to machine but requires slow cutting speed due to softness.
Features & Advantages
  • Integrated design, easy installation: The eyelet and expansion bolt are manufactured as a single piece, eliminating the need for additional assembly. Installation simply involves inserting it into the pre-drilled hole and tightening the nut.

  • Stable fixation, high load capacity: The expansion mechanism ensures reliable holding power in solid substrates (such as concrete and solid brick), making it suitable for hanging heavy objects.

  • Multiple material options, corrosion-resistant available: Common materials include 304 Stainless Steel, which offers good rust and corrosion resistance for both indoor and outdoor use. Carbon steel with zinc plating or higher-grade 316 Stainless Steel is also used in professional or specific applications for enhanced performance.
