S-91785A632 3/8"-16 x 2" ASME B18.6.3 Stainless Steel Truss Head Slotted Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction and passivated finish, ideal for harsh industrial environments and extended service life.
• Exceptional clamping force and load distribution from the wide truss head design, reducing surface damage and preventing pull-through in softer materials.
• High tensile strength of 100,000 psi ensures reliable performance under significant stress and vibration, minimizing the risk of fastener failure.
• Easy installation and removal with a standard slotted drive, compatible with common hand and power tools for efficient assembly and maintenance.
• Precise and reliable thread engagement due to the Class 2A thread fit and coarse UNC thread, providing consistent performance and reducing cross-threading risks.
• Full threading along the 2-inch length offers maximum grip and adjustability, suitable for a wide range of material thicknesses.
• Guaranteed material integrity with a Rockwell B100 hardness, balancing durability with necessary ductility to resist shearing and stripping.

Professional Applications & Engineering Value

This 3/8"-16 UNC x 2" Rounded Truss Head Slotted Screw is engineered from 18-8 Stainless Steel to address critical challenges in industrial assembly, including exposure to moisture, chemicals, and high-stress conditions. The passivated finish significantly enhances its corrosion resistance, making it a reliable choice for outdoor equipment, marine applications, and food processing machinery where sanitation and durability are paramount. The unique truss head provides a larger bearing surface than standard round heads, distributing clamp load effectively to prevent damage to soft substrates like plastics or composites. Combined with a coarse UNC thread and Class 2A fit, it ensures quick installation and secure fastening in wood, metal, and plastic assemblies, reducing assembly time and improving joint integrity in heavy-duty applications.
