BLAZER Security Screws

BLAZER Security Screws are drill screws made for metal siding and roofing applications, as used on metal roof replacement with exposed-fastener panels. They drill through steel of the stated thickness and fasten panels to the steel beneath. The BLAZER 3 point covers .036 in to .210 in of steel and the BLAZER 1 point covers .036 in to .090 in.

The Torx pin head gives maximum torque transfer and positive tool engagement, so installation takes less pressure and causes less slippage. The pin recess requires a matching drive bit, which gives a high degree of security. The screw is available in a button head for a neat appearance. The body is C1018-1022 carbon steel with a TRI-SEAL 1,000 hours salt spray coating for added corrosion protection. Typical uses are mini storage, prisons, government buildings, banks and dealerships.

• #12-14 BLAZER 3: 1-1/2 and 2 in long; drills .036 to .210 in of steel
• 1/4-14 BLAZER 1: 7/8 in long; drills .036 to .090 in of steel

Load bearing length is .625 in on the 1-1/2 in screw, .750 in on the 2 in screw and .250 in on the 7/8 in screw. Box quantity is 2.0M for each #12-14 length and 2.5M for the 1/4-14.

• Head: Torx pin head, available as a button head
• Drive: T-27 Torx pin recess; insert bits are supplied
• Washer: BOND-SEALER sealing washer, EPDM vulcanized to a 20 gauge galvanized backing
• Material: C1018-1022 carbon steel
• Coating: TRI-SEAL 1,000 hours salt spray
• Seating: drive the fastener until the EPDM sealant extrudes to the outer edge of the backing material. A slight circle of sealant at the edge is correct. Turned-up metal backing means too tight. Uncompressed sealant means too loose and forms no seal.
• Installation: screw gun at 2,000 RPM; do not use impact tools
