Value Collection 39248 Hex Head Cap Screw 1-1/4-7 X 7 in Grade 8

Product Description

The VALUE COLLECTION 39248 is a partially threaded hex head cap screw designed for heavy-duty fastening applications requiring high tensile strength. Manufactured from Grade 8 steel with a zinc yellow dichromate finish, this screw offers corrosion resistance alongside the elevated strength rating expected from Grade 8 fasteners. It features a 1-1/4-7 UNC thread size and a 7-inch length measured under the head. Produced to ASME B18.2.1 standards, it is suited for use by millwrights, maintenance mechanics, and structural assembly trades wherever a large-diameter, high-strength fastener is required.

This cap screw is appropriate for heavy structural assemblies, machinery mounting, and industrial maintenance applications where Grade 8 strength is specified. The partial threading allows for greater shank grip length, making it well suited for applications involving thick material stackups or where shear resistance is a priority. It is sold in a package quantity of two per order.

Key Features

• Grade 8 steel construction delivers high tensile and proof load strength for demanding fastening applications
• Zinc yellow dichromate finish provides corrosion protection in exposed or mildly harsh environments
• Partially threaded shank increases shear resistance and grip length through thick material
• 1-1/4-7 UNC thread form is a standard coarse-thread configuration for broad tool compatibility
• Manufactured to ASME B18.2.1 standards for dimensional consistency and interchangeability
• Sold as a package of 2 per unit

Compatibility

Designed as a standard UNC coarse-thread hex head cap screw for use in applications requiring a 1-1/4-7 thread size and Grade 8 strength rating per ASME B18.2.1.

Installation Notes

Installation is typically performed by millwrights, maintenance mechanics, or structural assembly technicians using appropriate hex drive tooling sized for a 1-1/4-inch hex head fastener. Verify that the mating tapped hole or nut meets Grade 8 or equivalent strength requirements before assembly. Follow applicable torque specifications from engineering documentation or a recognized fastener standard reference, as no torque value is specified in the product data. Inspect threads for damage before installation and ensure mating surfaces are clean and free of debris.
