Minerallac 59020J Zamac Nail-in Anchor 1/4x1-1/4

Product Description

The MINERALLAC 59020J is a zamac nail-in anchor designed for fast, tool-light fastening in concrete, block, and masonry substrates. Zamac is a zinc-based alloy known for its strength, corrosion resistance, and consistent dimensional tolerance, making it a reliable choice for conduit support, wire management fittings, and similar trade applications. At 0.25 inches in diameter and 1.25 inches in length, this anchor drives flush with a standard hammer, eliminating the need for pre-tapped holes or threaded inserts. Electricians and mechanical contractors reach for nail-in anchors when speed matters and substrate conditions allow direct drive installation.

This anchor is suited for light-duty to medium-duty fastening tasks in residential and commercial construction. Typical applications include securing conduit straps, cable supports, wire hangers, and similar electrical or mechanical hardware directly to concrete walls, ceilings, or floors. The nail-in design is especially practical in overhead and tight-clearance installations where setting a traditional wedge or screw anchor would slow the job down. It is a staple item on electrical rough-in and retrofit projects alike.

Key Features

• Zamac zinc-alloy construction provides corrosion resistance and consistent holding strength
• 0.25 inch diameter by 1.25 inch length suits standard conduit strap and wire support fastening
• Nail-in drive style installs with a hammer — no drill required for anchor setting
• Compact form factor works in tight clearances and overhead applications
• Lightweight at 0.02 pounds per anchor, minimizing load on supported hardware

Compatibility

Designed as an OEM-style nail-in anchor for use with standard 0.25 inch conduit straps, pipe hangers, and wire management clips fastened to concrete or masonry surfaces.

Installation Notes

Installation is performed by licensed electricians or mechanical contractors working to NEC or applicable local code requirements. Pre-drill the substrate to the manufacturer-specified hole diameter and depth before driving the anchor. Ensure the substrate is free of cracks or voids at the fastener location that could compromise holding strength. Never exceed the load rating for the anchor size and substrate type specified in the project drawings.
