Hillman Fasteners 47720 Drywall Screws 10x3.75 in 5 Lb

Product Description

The HILLMAN FASTENERS 47720 is a bulk box of black phosphate coarse-thread drywall screws sized 10 x 3.75 inches. These fasteners are designed for securing drywall panels to wood framing in residential and light commercial construction. The black phosphate finish reduces surface glare, provides light corrosion resistance during installation, and helps the screw countersink cleanly without tearing the drywall face paper. The coarse thread pattern bites aggressively into wood studs, delivering strong pull-through resistance. Each box contains 5 pounds of screws, making it a practical bulk supply for larger jobs. Drywall installers, general contractors, and finish carpenters rely on this size for thick single-layer or double-layer drywall applications where a standard 1.25-inch screw falls short.

These screws are suited for wood-framed wall and ceiling assemblies where panels require deeper fastener penetration into the stud. The 3.75-inch length is commonly used in double-layer drywall systems, thick substrate assemblies, or where framing members are set back from the panel surface. The coarse thread is appropriate for softwood and engineered wood framing. This product is packaged in boxes of 5 pounds each and is sold in a case pack of 4 boxes, providing a total of 20 pounds of fasteners per case for high-volume production work.

Key Features

• Black phosphate finish for reduced glare and light corrosion resistance during installation
• Coarse thread pattern for strong bite in softwood and engineered wood framing
• 3.75-inch length suited for double-layer drywall and thick substrate assemblies
• Size 10 shank provides solid pull-through resistance without over-driving
• 5-pound bulk box reduces job-site restocking frequency

Compatibility

Designed for use with standard wood-framed wall and ceiling assemblies requiring a coarse-thread drywall screw. Compatible with softwood lumber and engineered wood framing members commonly found in residential and light commercial construction.

Installation Notes

Installation is performed by drywall installers and general contractors using a screw gun or drill with a drywall dimpler bit set to proper depth. Drive screws until the head is just below the drywall surface without breaking the face paper. Follow local building codes and manufacturer panel guidelines for fastener spacing and pattern. Avoid over-driving, which can compromise holding strength and require patching.
