Anchors, Bits, & Screws

Anchors, bits, and screws are essential fastening components used across residential, commercial, and industrial installations. RSP Supply carries a full line of anchors, drill bits, and screws from LH Dottie, designed to provide dependable performance when fastening into materials such as drywall, wood, metal, masonry, and concrete. These products support safe, secure installations in electrical, construction, and maintenance applications.

Anchors are used when screws alone cannot provide sufficient holding strength. Common options include plastic wall anchors for drywall, which expand to create a secure grip, and toggle bolts that spread behind hollow walls to support heavier loads. Masonry anchors are engineered for concrete, brick, and block, delivering reliable holding power in demanding environments. Selecting the correct anchor type helps ensure structural integrity and long-term reliability.

Bits and screws complete the fastening system by allowing precise hole creation and secure fastening. Drill bits are available in multiple styles, including twist bits for wood, metal, and plastic, and carbide-tipped masonry bits for harder surfaces. Screws range from wood screws and sheet metal screws to machine screws and self-tapping designs, with specialty coatings available for corrosion resistance in outdoor or industrial settings. Together, these components provide versatile solutions for a wide range of fastening needs.

FAQs

Q: When should an anchor be used instead of a screw alone?
Anchors should be used when fastening into materials like drywall, masonry, or concrete where screws alone may not provide adequate holding strength.

Q: What types of anchors are commonly used?
Common anchors include plastic wall anchors, toggle bolts, and masonry anchors, each designed for specific materials and load requirements.

Twist bits are used for drilling into wood, metal, and plastic, while masonry bits are designed with carbide tips for drilling into brick, concrete, and stone.

Q: What are self-tapping screws?
Self-tapping screws create their own threads as they are driven into the material, eliminating the need for pre-tapped holes.
