Ribs under the head dig into the surface of soft metal and plastic to keep the bolt from turning when tightening a nut. These bolts are commonly used in tight spaces with moving parts, such as grain elevators and other belting systems.

Threaded inserts are cylindrical fasteners with internal or external threads, designed to be inserted into a pre-drilled hole to provide a threaded receptacle for bolts, screws, or other threaded fasteners. They are commonly used to reinforce or repair threads in materials such as metal, plastic, or wood, especially when the original threads are damaged or when a stronger, more durable thread is needed. Threaded inserts come in various materials, sizes, and thread types to suit different applications, and they can be installed using methods such as press-in, heat-set, or self-tapping techniques. Brass inserts are stronger than aluminum and other brass alloys but not as strong as stainless steel inserts. Aluminum inserts are 70% lighter than brass and stainless steel inserts, have good corrosion resistance, and are lead-free and can be safely recycled. Stainless steel inserts are stronger than brass and aluminum inserts, have excellent corrosion resistance.

Chemical Anchors: Strong, Reliable Support for Masonry. Used with adhesive in bricks and hollow blocks, such as cinder blocks, these mesh tubes create a stronger hold for rods and studs than other anchors. To install, first fill tubes with adhesive (sold separately) and press them into a drilled hole. Hold tubes in place by pressing the tab against your block, and insert a rod into them. The rod will push the adhesive out of the mesh screen, forming a plug that keeps the rod in place once the adhesive dries.
