Product Description

    The fish fin expansion bolt is a mechanical anchor that comes pre-assembled for fixing items into dense base materials including concrete and masonry. It works through a simple mechanism: an inner bolt and an outer expansion sleeve. As the nut is tightened, the bolt is pulled back, forcing the sleeve to expand and lock tightly against the sides of the drilled hole. This creates a claw-like grip, delivering reliable frictional force.

 
 
  • Copper material: Zinc copper alloy nuts, etc.
  • 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
  • Self-locking nut, locking nut, four-claw nut, driving nut safety nut
  • Thin rod screw connection nut, self-locking hexagonal cap nut
  • Special anchor screw nut, hexagonal crown thin nut, suspension ring nut
  • Welded square nut, welded hexagon nut, fastening nut, inserted round nut
  • Fine teeth all metal hexagonal flange face lock nut
  • Round nut with slot, round nut with hole on side/end, small round nut
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.
