Description

SFS 1297832 1/4-14 x 4-Inch Type B 304 Stainless Steel Self-Tapping Metal-to-Metal Screw – Hex Washer Head – EPDM Bonded Sealing Washer

Elite 304 Stainless Steel. Heavy-Duty Type B Thread Grip. Leak-Free Bonded EPDM Washer.

The SFS 1297832 1/4-14 x 4" Self-Tapping Metal Screw represents the industry's highest standard for structural fastening integrity in demanding exterior environments. Precision-machined from premium 304 grade stainless steel (A2), this 4-inch long structural fastener is specifically engineered for high-exposure building envelopes, coastal roofing designs, industrial chemical facilities, and rainscreen panels. It provides commercial metal building installers, cladding crews, and architectural sheet metal contractors with absolute immunity against galvanic corrosion and cosmetic rust bleeding, completely eliminating structural failure points down the line.

Uncompromising holding power and watertight sealing precision define the engineering behind this SFS masterpiece. This high-performance fastener is built with a Type B blunt tapping point and tight 14-pitch threads, custom-engineered to cut clean, high-torque mechanical pathways through pre-drilled pilots in thick sheet metal, heavy structural steel studs, and cold-rolled purlins. To guarantee complete protection against water intrusion in high-wind rain zones, it features a pre-assembled galvanized backing washer bonded to a resilient EPDM rubber seal. When driven home via its rugged hex washer head, the EPDM gasket compresses evenly to create a permanent, gas-tight barrier that dampens jobsite structural vibrations while stopping moisture leaks dead.

Why the SFS 1297832 304SS 4" Metal-to-Metal Screw Controls the Field:

  • Premium 304 Grade Stainless Steel: Offers maximum protection against coastal salt-spray, heavy smog, chemical washing, and acid rain layout conditions.
  • High-Volume 4-Inch Depth Reach: Provides the critical extended physical clearance needed to pass completely through deep insulation layers, composite panels, or thick spacer tracks.
  • Aggressive Type B Blunt Point: Custom-designed to tap cleanly into pre-drilled pilot holes, delivering vastly superior pull-out resistance compared to standard point geometries.
  • Bonded EPDM Sealing Gasket: Resilient rubber cushion absorbs thermal movement expansion while providing a permanent, watertight seal around the fastener hole.
  • Rugged Hex Washer Head Layout: Distributes driving torque evenly across the metal face, completely preventing tool slippage and head-shearing failures.

Frequently Asked Questions

+ What is the advantage of 304 Stainless Steel over standard 410 stainless or carbon steel screws?
Carbon steel rusts quickly, and 410 stainless steel contains high carbon content which makes it harder but still vulnerable to eventual surface rusting and "bleeding" stains. 304 Grade Stainless Steel provides premium chemical resistance due to its high nickel and chromium blend. It will not bleed ugly red rust down your building's finished metal panels, making it the required choice for coastal areas, food processing plants, and long-life architectural projects.
+ What exactly is a "Type B" point? Do I need to pre-drill pilot holes for this screw?
Yes, pre-drilling is required. A Type B screw is a self-tapping (thread-forming) fastener featuring a blunt, flat tip rather than a sharp drill point. It is engineered specifically to thread into pre-drilled pilot holes in metal sheet profiles. Because 304 stainless steel is relatively soft compared to hard structural carbon steel structural columns, a pre-drilled hole lets the Type B threads cut clean, deep, and incredibly strong mechanical tracks without risk of the screw tip twisting off or burning up.
+ What size pilot hole drill bit should I use for a 1/4-14 metal-to-metal application?
The correct pilot hole diameter depends slightly on the combined thickness of the metal sheets you are fastening. For standard metal-to-metal applications using a 1/4" fastener, a #3 (0.213") or a 7/32" (0.218") drill bit is widely utilized. Always test a sample hole in your scrap material first to ensure the Type B threads form a deep, high-torque mechanical bite without requiring excessive force to drive home.
+ How tightly should I drive this screw to ensure the bonded washer seals correctly?
You should drive the screw until the metal backing washer seats flat against the panel and the EPDM rubber edge squishes out slightly past the metal lip. Avoid over-torquing the screw with a high-impact gun, as over-tightening can crush, split, or invert the EPDM seal, which ruins its weatherproofing capability and causes moisture leaks. For best results, use a standard drill-driver fitted with an adjustable torque clutch or a dedicated depth-sensing screwgun.
