Pin Type Anchor Fasteners

About Pin Type Anchor Fasteners

A Pin Type Bullet Anchor is a heavy-duty, self-expanding mechanical fastener designed for anchoring applications in solid base materials such as concrete, brick, and stone. It consists of a bullet-shaped steel body with internal threads and an expansion pin. When the pin is driven into the anchor body, it forces the anchors bottom section to expand, creating a strong mechanical interlock with the substrate.

Key Technical Features:

• Material: Typically manufactured from carbon steel, zinc-plated steel, or stainless steel grades (SS 304/316) for enhanced corrosion resistance.

• Design: Bullet-shaped body with internal threading and a separate steel expansion pin that delivers reliable wedge-type expansion.

• Installation Method: Insert the anchor into a pre-drilled hole and hammer the pin until it is fully seated, causing uniform radial expansion for secure anchoring.

• Thread Type: Metric or imperial internal threads for compatibility with bolts, machine screws, or threaded rods.

• Load Capacity: Provides high tensile and shear load performance suitable for medium to heavy-duty fixing applications.

• Hole Requirement: Requires precise hole diameter and depth as per anchor size for maximum holding strength.

• Performance: Offers strong vibration resistance and long-term stability due to its positive locking mechanism.

Applications:

• Mounting brackets, base plates, railings, and metal frameworks

• Electrical, mechanical, and plumbing installations

• Sign boards, cable trays, faade supports, and machinery fixtures

• Suitable for indoor and outdoor construction fixings

Advantages:

• Easy and quick hammer-set installation

• Strong and reliable expansion in concrete

• Corrosion-resistant options available

• Suitable for overhead and vertical applications

• High pull-out and shear strength
