SHEET METAL SCREWS

Thin Metal's Best Friend

Sheet metal screws are ideal for connecting thin metal sheets. They come in various head styles like flat, oval, and round, and in lengths ranging from 1/8” to 2”. Pre-drilled or punched starting holes are necessary, and the screw's diameter should slightly exceed these.

MACHINE SCREWS

Machine Screws: Precision in Metal

Machine screws are designed for pre-threaded holes in metal, with some capable of cutting their own threads. These screws come in round, oval, flat, and fillister head styles, and their size is indicated by diameter, thread count, and length.

WOOD SCREWS

The Carpenter's Choice

Wood screws are used primarily for fastening wood. Available in steel, stainless steel, aluminum, or brass, these screws have various coatings for protection and aesthetics. Their threads usually run three-fourths of their length.

LAG SCREWS

For Heavy-Duty Applications

Lag screws, or lag bolts, are stronger and larger than standard wood screws. They are partially threaded with a hex head and require pre-drilled holes for installation, ideal for materials that need to bear heavy loads.

STRUCTURAL SCREWS

A Construction Essential

Structural, or construction, screws are a modern alternative to lag screws. They are self-tapping, eliminating the need for pre-drilling. These screws are heat-treated for strength and have drive heads designed for improved torque and minimal stripping.

CARRIAGE AND MACHINE BOLTS

Versatile and Strong

Carriage bolts have a square shoulder under the head, preventing rotation during tightening. Machine bolts, used with nuts or in threaded holes, come in various head styles for different applications, from joint fastening to flush surface integration.

MACHINE BOLTS

Machine Bolts: Versatility in Fastening

Machine bolts come in various head types - regular, square, hex, button, or countersunk. Each type serves a specific purpose:

• Square Heads: Ideal for fastening joints in applications where the demand on the bolt isn't extreme.
• Button Heads: They provide a smooth surface, perfect for areas where protrusions can be problematic.
• Countersunk Heads: These are best for creating a flush surface, maintaining a clean and flat look.
• Hex Bolts and Machine Screws: Often used interchangeably, they're versatile for various applications.
• Stove Bolts: Another type, known for their specific applications in smaller-scale projects.

NUTS

Securing the Bond

Nuts are threaded onto bolts to tighten and secure connections. The variety includes:

• Hex and Square Nuts: Commonly used and known for their reliability.
• Slotted Nuts: Feature top slots for cotter pins, preventing loosening.
• Wing and Knurled Nuts: Ideal for manual adjustments without tools.
• Locknuts: Have a self-locking feature for a secure fit without additional hardware.
• Tee Nuts: Perfect for fastening wood or composite materials, leaving no visible fastener.

COTTER PINS

The Simple Yet Effective Lock

Cotter pins are a simple, yet effective, fastening device. Inserted into a hole of a bolt or shaft, they have an eye at one end to prevent passage through, with prongs at the other end bent back to secure the pin.

CAPS

Enhancing Appearance and Protection

Caps are used to cover fasteners, adding a finishing touch while tightening them. They often feature a high crown, enhancing the overall appearance of the project.

TURNBUCKLES

The Solution for Alignment and Tension

Turnbuckles are essential for tightening wires or bracing doors and gates. Their barrel-shaped design with threaded rods is perfect for pulling structures back into alignment.

WASHERS

The Unsung Heroes of Fastening

Washers play a vital role in distributing load and preventing damage to surfaces. Available in flat, countersunk, or flush types, they match the screw size used. Special types include fender washers for large holes and lock washers for securing nuts.

HOLLOW WALL ANCHORS

The Molly Bolt

Hollow wall anchors, commonly known as Molly bolts, are ideal for medium- to heavy-duty applications. These anchors consist of a metal sleeve and a screw. When installed, the sleeve expands inside the pre-drilled hole as the screw is turned, creating a secure hold. A unique feature of Molly bolts is that the screw can be removed and reinserted multiple times, making them ideal for mounting fixtures that might need to be adjusted or replaced.

TOGGLE BOLTS

The Heavy-Duty Solution

Toggle bolts are designed for mounting heavy items. They require a pilot hole slightly larger than the bolt itself. Once inserted into the hole, the bolt's holding arms open behind the wall, creating a strong grip as the screw is tightened. Toggle bolts come in various diameters, typically ranging from 1/8” to 1/2”. It’s crucial to assemble the fixture with the screw and holder before inserting it into the wall, ensuring a secure and stable mount.

WALL DRILL ANCHORS

The Self-Drilling Choice

Wall driller anchors are a convenient option for medium-duty tasks. These fasteners are designed to create their own hole in the drywall, eliminating the need for pre-drilling. Available in materials like plastic, nylon, or metal, wall driller anchors are easy to install and are suitable for hanging lighter items such as picture frames, small shelves, or decorative pieces.
