PIN TYPE ANCHOR FASTENER

Product Specification :
A Pin Type Anchor Fastener (also known as a Hammer Drive Anchor or Strike Anchor) is a heavy-duty, torque-independent expansion anchor. Unlike standard Rawlbolts that require a wrench to expand, these anchors are activated by driving a hardened steel pin into the center of the bolt, which forces the sleeve to expand against the walls of the drill hole.

1. Anatomy & Design
The Pin Type Anchor is comprised of three main parts:
The Body: A hollow, internally tapered sleeve with a pre-cut expansion slot at the base.
The Drive Pin: A hardened, high-tensile steel pin that sits inside the body.
The Washer/Nut: Used to secure the fixture against the base material.

2. Material & Finish
Feature    Specification
Body Material    Carbon Steel or Stainless Steel (AISI 304/316).
Pin Material    High-Carbon Hardened Steel.
Finish    Zinc Plating (standard) or Hot-Dip Galvanized for outdoor use.
Expansion Type    Internal wedge expansion (non-rotational).

3. Key Technical Specifications
Installation Method: Through-fixing (you can drill and install through the fixture).
Hole Diameter: The drill bit size is equal to the nominal diameter of the anchor (e.g., a 10mm anchor requires a 10mm hole).
Load Type: Static loads; excellent for high-shear applications.
Base Materials: Suitable for high-density Concrete, Solid Brick, and Natural Stone.

4. Advantages & Limitations
Advantages    Limitations
Speed: Fastest heavy-duty anchor to install (drill, tap, strike).    Permanent: Extremely difficult to remove once the pin is driven.
Visual Inspection: If the pin is flush with the head, it is correctly installed.    Shock Sensitive: Brittle masonry may crack under the impact.
Torque Independent: No torque wrench required; ideal for rapid site work.    Non-Adjustable: Cannot be tightened further once set.

5. Installation Steps
Drill: Use a masonry bit to drill a hole through the fixture and into the base material to the specified depth.
Clean: Clear the hole of all dust (dust acts as a lubricant and can cause pull-out).
Insert: Hammer the anchor into the hole until the washer is flush against the fixture.
Set: Strike the center pin firmly with a hammer until it is flush with the top of the anchor.

6. Common Applications
Structural Steel: Fixing angle irons, brackets, and base plates to concrete floors.
Safety Equipment: Installing handrails, guardrails, and stadium seating.
Infrastructure: Mounting heavy signage and electrical cable trays in tunnels or warehouses.
