Expansion Anchor Bolt

This page showcases S-SEN Metal Expansion Anchor Bolt, a professional fastening solution for construction, installation and equipment fixing. Sourced directly from Cangzhou Shengsen Hardware Products Co., Ltd., the product delivers reliable performance for concrete, brick wall and hard base material applications.

What is S-SEN Expansion Anchor Bolt

S-SEN Expansion Anchor Bolt is a professional fastener that achieves tightening through a physical expansion mechanism.

It uses a wedge-shaped slope to generate frictional gripping force, ideal for building reinforcement, home installation and equipment fixing.

Core Components

• Screw rod
• Expansion tube
• Nut
• Washer

Working Principle

Tighten the nut → The conical screw end compresses the expansion tube → Tube expands and grips the drilled hole → Stable anchoring is formed.

Product Features

Structural Design

• Screw tail adopts a conical structure
• Expansion tube with slits on the wall (metal/plastic available)
• Standardized matching parts for stable assembly

Expansion & Fastening

• Tightening the nut drives the screw outward to expand the tube
• Expansion tube fits tightly with the base material inner wall
• Cone self-locking angle enhances anti-loosening performance

Key Performance Advantages

• Higher tensile and shear strength than ordinary screws
• Stable fastening on concrete, brick walls and hard base materials
• Physical expansion structure reduces loosening risk
