Complete Hardware Solutions for HVAC Systems
Fasteners, Access Hardware, Sealants, and More
Commercial HVAC units are vital in maintaining a comfortable and safe environment for employees and visitors through heating, ventilation, and air conditioning. They are complex systems routinely housed in special enclosures that need to be sturdy, secure, and easily accessible.
From access hardware to fasteners and chemical solutions, Austin Hardware carries a vast inventory of hardware solutions to fulfill the unique needs of commercial HVAC enclosures and air filtration system manufacturers. Our team is ready to help manufacturers address the special requirements and considerations for their HVAC project, like energy regulations, climate factors, and size.

Fasteners
Mechanical fasteners are key parts used in the design of your HVAC enclosure to make sure they remain securely intact. Whether you need to install thermostats and ductwork or assemble furnaces, boilers, air handlers, and so much more, we have the right fastener for any application.
Different types of fasteners can be helpful at different points in your HVAC project. We carry a wide variety of fastener types for all your HVAC enclosure applications.
- Screws are used to secure sheet panels, components, and frames. Wood screws are appropriate for securing HVAC components to wooden surfaces. Self-tapping screws work well on sheet metal ductwork.
- Bolts, Nuts, and Structural Rivets are necessary for strong structural connections, including suspending ductwork, fastening parts, securing electrical panels, and suspending pipelines.
- Blind Rivets are perfect for joining sheet metal and especially useful for joining two materials together when only one side is accessible.

Access Hardware
Access hardware plays a crucial role in preserving the life and function of industrial equipment, including HVAC systems. Secure your HVAC equipment and enhance user experience with one of the largest selections of access hardware for HVAC enclosures. Featuring the highest quality latches, handles, hinges, door holdbacks, and more, Austin Hardware is here to help you succeed in your HVAC business. Plus, our inventory is packed with access hardware for HVAC enclosures from top suppliers like Eberhard, Southco, Hansen, Enginia, and many others.
Handles
Handles come in different materials, mounting options, and enhanced features for safety and health. Our selection of in-stock non-, key-, and padlocking handles runs the gamut of styles and sizes for HVAC enclosures. Different styles and varieties have different benefits:
• Ergonomic handles provide increased comfort.
• T-handles and L-handles offer extra security.
• Recessed handles are beneficial for preventing obstruction.
Latches
These safe locking systems are necessary for a secure HVAC system. Varieties include:
• Flexible draw latches: securely lock two components together.
• Paddle latches: a widely used type of latch for its user friendliness.
• Folding-T latch: simple operation, security, and pleasing aesthetics make this a popular choice.
Finger pull latches
Hinges
Choose quality hinges with special resistance to rust and corrosion to enhance the performance lifespan of HVAC systems. We have one of the largest selections of hinge types available for HVAC enclosures, including strap, butt, lift-off, continuous (piano), and more.
• Butt hinges are the most common variety, recognizable by its two matching leaves. Its reliability makes it beneficial HVAC equipment that needs to be opened frequently for repairs and inspections.
• Continuous (piano hinges) are suitable for HVAC enclosures in harsh environments due to its strong chemical resistance to oil and seawater.
Tensorgrip® Spray Adhesives offer the perfect solution for superior insulation and lasting performance. In our latest partnership spotlight video, Austin Hardware's own William Isham explains how Tensorgrip P323 makes it faster and safer to bond fiberglass insulation to metal sheeting while achieving more reliable results.
