Hillman Fasteners 41821 Ribbed Plastic Anchor 8-10-12 25 Pack

Product Description

The HILLMAN FASTENERS 41821 is a ribbed plastic wall anchor packaged with screws, sized to accept No. 8, No. 10, and No. 12 fasteners. Ribbed anchors expand against the wall cavity as the screw is driven in, creating a secure hold in drywall, plaster, and similar substrates. Each package contains 25 anchors with corresponding screws. The multi-size compatibility makes this a practical keep-on-the-truck supply for HVAC techs, plumbers, electricians, and general contractors who regularly mount equipment, brackets, and fixtures to interior walls.

These anchors are suited for light-to-medium-duty fastening tasks in residential and commercial interiors. Common applications include mounting thermostat sub-bases, low-voltage control device brackets, electrical junction box supports, pipe hangers, and access panel frames to drywall or plaster walls. The included screws eliminate the need to source separate hardware, making field use straightforward.

Key Features

• Accepts No. 8, No. 10, and No. 12 screws — three common trade sizes in one pack
• Ribbed exterior grips the wall cavity as the screw is driven, resisting pull-out and rotation
• Screws included — no need to match separate hardware on the job
• 25-piece pack quantity supports multi-point mounting tasks without reordering
• Plastic construction resists corrosion in interior environments

Compatibility

Designed for use in drywall and plaster wall substrates requiring No. 8, No. 10, or No. 12 screw anchoring in standard interior fastening applications.

Installation Notes

Installation requires a drill or rotary tool to bore a pilot hole sized to the anchor diameter before seating the anchor flush with the wall surface. Drive the included screw until snug — do not overtighten, as over-driving can collapse the anchor body and reduce holding strength. Verify substrate type and wall thickness before selection; ribbed plastic anchors are intended for solid interior substrates such as drywall and plaster, not hollow metal stud flanges or masonry.
