The Ultimate Guide To Hollaender Set Screw Sizes

Hollaender Manufacturing Company is known for its reliable structural slip-on pipe fittings, which are easy to install and come with self-locking set screws. The set screws are available in various sizes, including 3/8-16 x 7/16, and are made of a special aluminum-magnesium alloy with Cadmium-plated steel. These screws are 100% salvageable and can be used with a range of pipe materials, including aluminum, galvanized steel, and stainless steel. Hollaender's fittings are versatile and can be used to create mounting systems for solar panels, with the added assurance of a 10-year warranty against corrosion.

Zinc-plated steel screws

When it comes to Hollaender set screws, zinc-plated steel is a common and popular choice for a variety of applications. These screws are designed to provide strong and reliable fastening, and the zinc plating adds a layer of protection and corrosion resistance. Here's some detailed information about zinc-plated steel screws and their specific applications:

The size of Hollaender set screws in zinc-plated steel typically ranges from #10-24 to 3/8-16. The most common sizes used are 1/4-20 and 5/16-18. These screws are designed to securely fasten aluminum profiles, panels, and other components together, ensuring a tight and robust assembly. The length of the screws can vary depending on the specific application and the thickness of the materials being joined.

It's important to select the right screw length to ensure a secure fit. Screws that are too long may protrude and cause obstructions or safety hazards, while screws that are too short may not provide sufficient clamping force. Hollaender set screws often come in a variety of lengths, allowing for flexibility in design and assembly.

When working with zinc-plated steel screws, it's crucial to consider the torque settings during installation. Over-tightening can strip the threads or damage the underlying material, while under-tightening may result in a loose connection. Following the manufacturer's torque recommendations ensures optimal performance and longevity of the fastening system.

In addition to the screw size and torque settings, it's worth noting that zinc-plated steel screws require proper care and maintenance, especially in harsh environments. The zinc plating provides good corrosion resistance, but it's not invincible. Regular inspection and maintenance, including checking for tightness and inspecting for any signs of corrosion, are crucial to ensure the long-term performance of the screws and the overall assembly.

Cadmium-plated steel screws

It is important to note that cadmium is a toxic cumulative poison, similar to mercury and lead. Therefore, it is essential to take the necessary precautions when handling these screws, such as wearing protective gear and washing hands after use.

Stainless steel screws

Set screws are used to exert pressure at the tip to hold objects in place, unlike regular screws that hold materials together with threads. When choosing a set screw, it is important to consider the type of surface it will be used on. For instance, flat-tipped set screws are ideal for flat surfaces, while oval-tipped screws are meant for U-shaped and V-shaped grooves and other sloped or angled surfaces.

Hollaender Manufacturing Company offers a range of stainless steel set screws for its fittings. The standard material for Hollaender set screws is an aluminium-magnesium alloy, which is highly corrosion-resistant and can be used with any type of pipe, including steel and stainless steel. The set screws are designed for quick and easy installation, with no threading, welding, nuts, bolts, or washers required.

Aluminium-magnesium alloy screws

Hollaender Manufacturing offers set screws with a size of 3/8-16 x 7/16 inches. While I could not find specific information about Hollaender screws, I discovered some details about aluminium-magnesium alloy screws in general.

When designing joints in magnesium, engineers must consider its limited shear strength. To address this, the length of engagement for screws should be around 2 to 2.5 times the screw diameter. This ensures a secure and stable joint. Additionally, to prevent galvanic corrosion, it is essential to use a non-conductive screw coating or insulating sealants.

One type of screw that is well-suited for magnesium and aluminium-magnesium alloys is the REMFORM® II F™ screw. These screws are designed to form their own threads in untapped holes, eliminating the need for pre-tapping and reducing costs. They offer increased pull-out and vibrational loosening resistance, and their lead threads facilitate alignment, preventing blockage.

Threaded screw sleeves made of stainless steel are another option for repairing incorrect threading or damaged internal threads in aluminium-magnesium alloys. These sleeves improve thread strength and wear resistance while providing excellent connection performance.

Hex keys are typically designated by their socket size and are available in a variety of sizes. They can be sold individually or as part of a kit that includes multiple sizes. Hex keys are commonly made from hardened steel and are formed from a single piece of steel rod with blunt ends that fit into the screw sockets. The rods are bent to 90 degrees, creating two arms of unequal length in an "L" shape. The long arm is typically used to hold and twist the key, generating torque at the tip of the short arm. However, the short arm can also be used to access screws in tight spaces or to turn screws faster, albeit with reduced torque.
