Product Overview
IKING Round Self-Locking Washers are designed to secure thermal and acoustic insulation materials over insulation pins, weld pins, and lacing anchors. Once the insulation material is positioned over the pin, the washer is pressed manually or with a simple tool onto the spindle. The multi-lanced center hole grips the pin securely, establishing a quick, permanent, and vibration-resistant mechanical hold.

Frequently Asked Questions (FAQ)
Q1: What hole size washer do I need for my insulation pins?
A: The hole size must match the gauge/diameter of your pin. Common sizes include 12 GA (2.7mm) for standard self-adhesive pins and 10 GA (3.4mm) for heavy-duty weld pins.
Q2: What is the difference between Galvanized and Stainless Steel washers?
A: Galvanized steel is cost-effective and suitable for standard indoor HVAC applications. Stainless steel (SS304/SS316) provides superior corrosion resistance for outdoor, chemical, marine, or high-temperature environments.
Q3: Can I request samples before placing a bulk order?
A: Yes, IKING provides free standard samples for quality testing and pin fitment check.
