self-clinching blind nuts provide permanently mounted blind threads in metal sheets as thin as 1 mm.
Provides barrier to protect threads against foreign matter. Protects internal components from intrusion of screws.

Captive screws (also referred to as captivated fasteners or captive bolts) typically involve multiple components, which can result in higher production costs and increased importance for manufacturers. This specialization leads to a diverse range of features with various combinations tailored to specific applications. However, the fundamental principle remains consistent: a screw is securely held within a panel, either directly or through a separate retaining mechanism. Concerns regarding cross-threading can be addressed by incorporating a MAThread®, which introduces a curvature to the initial threads to ensure proper alignment. Certain products feature a knob cap screw or thumb screw for tool-free installation, while others may recess the screw within the retainer to discourage manual disassembly.

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.

Also known as wedge anchors, the base expands as you tighten the nut for a secure hold in concrete. They're often used to anchor machinery. Pull-out strength and shear strength values are 25% of the ultimate values.

Zinc-plated and zinc yellow-chromate plated steel anchors are corrosion resistant in wet environments.

Galvanized steel anchors are more corrosion resistant than zinc-plated steel anchors. They must be used with other galvanized fasteners.

ICC listed anchors are often required for new construction. Anchors listed for cracked concrete are often required in environments which may cause concrete to crack during the life of the anchor.

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.
