As a result, we deliver factory-direct pricing, consistent adhesive quality, and fast delivery. Similarly, this applies to all your HVAC duct, metal building, and acoustic insulation projects.
In addition, we produce these peel and stick insulation hangers with a pressure-sensitive adhesive backing. Meanwhile, we supply them with self-locking washers (speed clips) as matched components. Therefore, mechanical contractors and insulation fabricators rely on them for fast, clean insulation attachment without welding equipment.

| 12 GA (2.7 mm) | 2″ – 6″ | 2″ × 2″ | 0.4 mm | Pressure Sensitive | Metal building insulation |
| 14 GA (2.0 mm) | 1″ – 4″ | 1″ × 1″ | 0.3 mm | Pressure Sensitive | Light insulation & acoustic panels |
| 12 GA (2.7 mm) | 62 mm – 115 mm | 50 × 50 mm | 0.4 mm | PE Foam Tape | Marine engine room & compressor enclosure |
Material & Adhesive Specifications for Self Stick Insulation Pins
- To begin with, we use high-strength galvanized steel as the standard material for the pin and base plate. This provides reliable corrosion resistance for our self adhesive insulation pins.
- Moreover, the base plate is fabricated from galvanized steel sheet DX 51 D with a zinc coating of 275 g/m² on both sides[reference:1].
- Additionally, we apply a pressure-sensitive adhesive tape made from cross-linked polyethylene (PE) foam laminated with synthetic rubber resin adhesive. The adhesive is protected by a wax paper release liner until installation[reference:2].
- Furthermore, our self adhesive pins achieve a tensile strength of 1.3 KN/m per ASTM D 882 and a shear strength of 600 ks per FTM.2 / Finat.8 / PSTC.7[reference:3].
- For special orders, we supply aluminum and stainless steel pins for corrosion-sensitive or high-temperature applications.
- Finally, we offer OEM & ODM — we customize pin diameter, length, base dimensions, adhesive type, and packaging according to your specifications.
How Self Adhesive Insulation Pins Work — Peel & Stick Fastening
In fact, the self adhesive weld pin offers a clean, weld-free fastening method for insulation materials. Furthermore, it is ideal for surfaces where welding is not practical or permitted.
To begin with, you clean the mounting surface to remove dust, oil, and loose matter. Then, you peel off the protective release paper from the adhesive backing. Next, you press the base firmly against the surface to be insulated[reference:4]. After that, you impale the insulation material over the protruding pin. Finally, you secure the insulation with a self-locking washer (speed clip) pressed onto the pin[reference:5].
Therefore, the self adhesive method eliminates the need for welding equipment, adhesives, and curing time. As a result, contractors can install insulation quickly and cleanly with minimal tools.
Key Advantages of Self Adhesive Insulation Pins
- First, the peel and stick backing installs in seconds without welding, drilling, or messy adhesives.
- Second, the pressure-sensitive adhesive bonds firmly to clean metal, concrete, and wood surfaces[reference:6].
- Third, the self-locking washer presses onto the pin and locks the insulation securely in position.
- Finally, only the pin and washer are needed. No through-holes, no secondary operations, and no special tools for assembly.
Self-Locking Washers — Speed Clips for Insulation Retention
In addition, the self-locking washer is a critical accessory for completing the insulation fastening operation. Furthermore, we supply these washers as a matched component with our self adhesive pins.
To begin with, you simply press the self-locking washer (also called a speed clip or dome cap) onto the pin up against the insulation. Meanwhile, the domed, multi-lanced hole design provides positive locking. Then, you clip off or bend over the remaining portion of the pin for a permanent attachment[reference:7].
Self-Locking Washer Specifications
- First, we offer round and square self-locking washers in various sizes.
- Second, standard diameters include 1″, 1-3/16″, 1-1/2″, and 2″.
- Third, standard thickness is 0.015″ nominal, formed from galvanized steel.
- Finally, we also supply aluminum and stainless steel washers for special applications.

- As a result of their Corrosion Resistance, the galvanized pin and base resist rust in humid or outdoor environments.
- Finally, we provide Direct Factory Support. Tarco Industry provides technical guidance, samples, and custom production.
How to Install Self Adhesive Insulation Pins
- First, prepare the surface. Clean the mounting surface to remove dust, oil, moisture, and loose matter. Ensure the surface is dry and smooth.
- Then, peel off the release paper. Remove the wax paper backing from the adhesive base, taking care not to touch the adhesive surface.
- Next, press the pin into place. Position the hanger pin at the desired location and press the base firmly against the surface. Apply steady pressure for a few seconds to ensure full adhesive contact.
- After that, impale the insulation. Push the insulation material over the pin until it rests against the base or the mounting surface.
- Finally, secure with self-locking washer. Press the self-locking washer onto the pin up against the insulation. Clip off or bend over the remaining pin portion for a permanent attachment.
Applications & Industries for Self Adhesive Insulation Pins
- For instance, in HVAC duct systems, contractors use our pins to attach duct liner and external insulation to sheet metal ducts[reference:8].
- Also, in metal building insulation, they secure insulation to metal building walls, roofs, and ceilings.
