Hammer-Drive Anchor (Hammer Fix Anchor) | Rapid, High-Speed Anchoring for Light to Medium Duty
Product Overview
The Hammer-Drive Anchor is a simple, efficient, and cost-effective mechanical anchor designed for quick installation into solid concrete, brick, or solid masonry. It is a single-unit assembly consisting of a slotted expansion sleeve, a hardened steel drive pin (nail), and an integrated washer head. Installation is achieved solely by hammering the drive pin, which forces the sleeve to expand and lock securely within the pre-drilled hole. Its primary advantage is exceptional installation speed, making it ideal for high-volume, light-to-medium duty fastening applications where removability is not required.
Key Advantages
Extremely Fast Installation: No tools required beyond a hammer and drill. The “hammer-set” design allows for rapid installation, significantly reducing labor time.
One-Piece Design: Pre-assembled sleeve and pin eliminate loose parts, simplifying handling and inventory.
Ideal for Overhead & Blind-Hole Applications: Can be installed in any orientation, including directly upward, as gravity does not affect the setting mechanism.
Cost-Effective: Low unit cost combined with minimal installation effort provides excellent value for high-count projects.
Good Holding Power in Solid Base Materials: Provides reliable tensile and shear strength for a wide range of non-structural fixtures.
Material Specifications & Components
| Component | Material | Standard / Treatment | Purpose |
|---|---|---|---|
| Expansion Sleeve | Low Carbon Steel | Zinc Plated (typically) | Expands to create a tight friction lock within the drilled hole. |
| Drive Pin (Nail) | Hardened Medium Carbon Steel | Heat Treated, Zinc Plated | Transfers hammer impact to expand the sleeve; provides core strength. |
| Washer Head | Integral part of the sleeve | – | Distributes load and prevents the anchor from pulling through the fixture. |
Product Series & Specifications
Design Standard: Conforms to general dimensional and performance guidelines recognized in construction. Often supplied to meet commercial specifications rather than a single ISO/DIN standard.
Drive Types: Standard (domed washer head) and Flat Head (for countersunk applications).
Kích thước: Commonly available in diameters from 1/4″ (6mm) to 3/8″ (10mm) and lengths from 1″ (25mm) to 3″ (75mm), suitable for fixture thicknesses up to the anchor’s embedment depth.
Packaging: Bulk boxes or convenient clip-strips for retail and jobsite use.
Available Finishes
Electro-Zinc Plated (Standard): Provides basic corrosion resistance for indoor or protected outdoor use.
Hot-Dip Galvanized (HDG): For anchors requiring higher corrosion resistance in exposed environments.
Stainless Steel (304/316): Available for highly corrosive environments or specific chemical resistance requirements.
Installation Guidelines
Drill Hole: Drill a hole in the base material with a carbide-tipped masonry bit. The hole diameter must match the anchor diameter exactly, and the depth must exceed the anchor length.
Clean Hole: Remove all dust from the hole using a brush, air, or vacuum.
Insert Anchor: Place the anchor through the fixture and into the clean hole until the washer head is flush against the surface.
Drive Pin: Using a standard hammer, strike the drive pin squarely until the pin head is flush with or slightly below the top of the sleeve. The anchor is now set.
Note: Once set, the anchor is not removable without destroying it. Ensure correct placement before final driving.
Typical Applications
Electrical & Plumbing: Fastening conduit clamps, pipe hangers, and junction boxes to concrete walls and ceilings.
General Construction: Installing wall plates, light-gauge metal framing, and sill plates.
Facility Maintenance: Mounting signage, small shelves, handrails, and brackets to masonry walls.
Light Industrial: Securing machinery skids, workbench legs, and storage rack uprights to concrete floors.
Quality Assurance
Our Hammer-Drive Anchors are manufactured under a controlled quality system. Production includes dimensional checks, material verification, and performance testing (such as proof-load testing in concrete) to ensure consistent holding values and reliable field performance.
Manufacturing Partner
Công ty TNHH Sản xuất Phụ kiện Gắn kết Hebei Wohe. specializes in the high-volume production of practical, value-driven fastening solutions like the Hammer-Drive Anchor. Our efficient manufacturing process combines precision stamping for the sleeves with automated heading for the drive pins, ensuring a consistent and reliable product.

Availability: Wide range of standard sizes readily available for shipment.
Customization: Limited custom lengths, head markings, or packaging options are available for large-volume orders.
MOQ: Typically low, starting from 5,000 pieces per size, due to standard production runs.
Lead Time: Standard items: 15-20 working days.
Note: This anchor is designed for solid base materials only. It is not recommended for use in hollow block, lightweight concrete, or materials with low compressive strength. Always verify the anchor’s pull-out and shear values are suitable for the specific load and application. For critical or overhead safety applications, consult an engineer.
