1/4" Type AB Metal Self-Tapping Screw, HH, 304 Stainless | TAB-S3-14

• Zinc plated 304 stainless steel for corrosion resistance
• Available with no sealing washer or with bond seal washer
• Wax surface treatment for added lubricity
• Long lengths available for specialty applications

Metal panel to light and medium gauge metal application for use in high corrosive environments or with dissimilar metals where corrosion resistance and long building life are critical factors

• Install fasteners with 0–1000 rpm screw gun equipped with depth sensing nose piece.
• Use of impact guns or hammer drill is not recommended
• Metal thickness/drill bit size:
• 0.021"–0.026" (0.53 mm–0.66 mm);  drill bit size 1/8" (3.18 mm)
• 0.027"–0.050" (0.69 mm–1.27 mm);  drill bit size 3/16" (4.75 mm)
• 0.051"–0.075" (1.29 mm–1.9 mm);  drill bit size #8 (5.05 mm)
• 0.075"–0.104" (1.9 mm–2.64 mm); drill bit size #7 (5.11 mm)
• The hole size determines installations performance and pull out strength. Thickness is based on normal, single thickness purlin/girt or multiple material thickness combined for total.
• Fastener length should provide for a minimum of 3/16" penetration of fully developed threads into metal substrate.
