Value Collection NFC4103 Hammer Drive Concrete Anchor

Product Description

The VALUE COLLECTION NFC4103 is a hammer drive concrete anchor designed for fast, tool-minimal fastening into concrete, block, and masonry substrates. The anchor is manufactured from Zamac alloy with a zinc-plated finish for corrosion resistance in typical interior and sheltered exterior applications. It features a mushroom head profile, a 0.25 inch diameter body, a 0.25 inch required drill size, and an overall length of 1.25 inches. Installation requires only a hammer after drilling the pilot hole, making it a common choice where speed and repeatability matter on the job site. Licensed contractors, plumbers, electricians, and HVAC technicians use these anchors to secure conduit hangers, pipe straps, and equipment brackets to concrete surfaces.

This anchor is suited for light-duty fastening applications in residential and commercial settings where a pre-drilled 0.25 inch hole is made into concrete, brick, or block. Common install scenarios include securing low-voltage wiring supports, duct hangers, junction box brackets, and similar trade hardware to concrete walls, floors, and ceilings. The mushroom head seats flush-style against the work surface to provide a low-profile finished appearance after drive. Minimum embedment depth is 6.5 inches, which should be factored into substrate thickness requirements at the time of layout.

Key Features

• Zamac alloy construction provides adequate strength for light-duty masonry fastening
• Zinc-plated finish offers corrosion resistance in interior and sheltered environments
• Mushroom head profile delivers a low-profile, flush-seated appearance after installation
• Hammer-drive installation requires no setting tool beyond a standard hammer after pilot hole is drilled
• 0.25 inch body diameter matches a standard 0.25 inch carbide-tipped masonry drill bit
• Minimum embedment of 6.5 inches ensures positive anchor engagement in the base material

Compatibility

Designed as an OEM-style replacement and standard-use hammer drive concrete anchor for light-duty fastening applications in poured concrete, concrete block, and brick masonry substrates.

Installation Notes

Installation should be performed by a qualified tradesperson following applicable building and mechanical codes. Drill the pilot hole to the specified 0.25 inch diameter using a carbide-tipped masonry bit and clear all dust from the hole before driving the anchor. Verify that the substrate thickness is sufficient to achieve the required minimum embedment before layout and drilling. Do not install into cracked, spalled, or otherwise compromised masonry, and do not exceed the load ratings specified for this anchor type and substrate.
