Value Collection MP38466 Concrete Masonry Screw 1/4 in Hex Drive 25pk

Product Description

The VALUE COLLECTION MP38466 is a steel concrete masonry screw designed for anchoring into concrete, block, and masonry substrates. At 1/4 inch in diameter and 1-3/4 inches in overall length measured under the head, this tapper-style fastener uses a hex drive for reliable installation with standard hex-drive bits or impact drivers. Each package contains 25 screws and includes a drill bit sized for the required pilot hole. The ICC-ES ESR-2202 certification confirms code-compliant performance for anchoring applications where documented fastener approval is required by an inspector or engineer of record.

These masonry screws are suited for light-duty anchoring tasks in residential and commercial construction, including securing electrical conduit straps, junction box brackets, HVAC equipment supports, and mechanical system components to concrete slabs, CMU block walls, and poured concrete. The included drill bit allows a tech to go from bare wall to finished anchor without sourcing a separate carbide-tipped bit. Sold in a 25-count pack with a minimum order quantity of 1 pack, making them practical for single-job purchases or van stock replenishment.

Key Features

• ICC-ES ESR-2202 certified for code-compliant masonry anchoring applications
• Hex drive accepts standard hex bits and impact drivers for fast installation

• Steel construction for durability in structural anchoring scenarios
• 25-count pack with minimum order quantity of 1

Compatibility

Designed as a direct-anchor fastener for use in concrete, concrete block, and CMU masonry substrates where a 1/4 inch diameter tapper screw with hex drive is specified.

Installation Notes

Installation is typically performed by licensed electricians, plumbers, HVAC mechanics, or general contractors anchoring mechanical system components to masonry. Drill the pilot hole to the depth and diameter specified by the ICC-ES ESR-2202 approval document using the included bit before driving the screw. Follow local building code requirements and the applicable ICC fastener approval for minimum embedment depth and edge distance. Do not overdrive — strip-out in the pilot hole will compromise holding strength and require re-anchoring at a new location.
