L H Dottie Co 20 Tapered Anchor Collar Red 4-6-8

Product Description

The L H DOTTIE CO 20 is a tapered plastic anchor with collar, sized for use with number 4, 6, and 8 screws. The red color coding identifies the size range at a glance, reducing installation errors on busy job sites. Tapered anchors with collars are designed to expand against the base material as the screw is driven, creating a secure mechanical hold in drywall, masonry, or similar substrates. Electricians, plumbers, and general contractors reach for this type of fastener when securing brackets, conduit straps, junction boxes, and light fixtures to walls or ceilings where a threaded anchor is required.

This anchor is suited for light-duty fastening applications in residential and light commercial construction. The collar prevents the anchor from pulling through the surface during installation, keeping the anchor flush and properly seated. It works with standard number 4, 6, and 8 fasteners, making it a versatile option for common trade mounting tasks across multiple screw sizes. Sold individually, it can be ordered in the quantity needed for a specific job or stocked as part of a general fastener supply.

Installation Notes

A licensed electrician, plumber, or general contractor typically installs tapered anchors as part of a broader mounting or support task. Drill a hole sized to match the anchor diameter before insertion, then seat the anchor flush using hand pressure or a rubber mallet. Drive the appropriate screw straight and steadily to allow the anchor to expand evenly. Do not overdrive the screw, as this can crack the anchor body and reduce holding strength.
