Value Collection 88547286 Hex Socket Cap Screw 1-8 Unc

Product Description

The VALUE COLLECTION 88547286 is a hex socket cap screw designed for high-strength fastening applications in mechanical, industrial, and structural assemblies. This screw features a 1-8 UNC thread size with a 3.5-inch length under the head, manufactured from alloy steel with a black oxide coating for corrosion resistance. Driven with a 3/4-inch hex key, it is partially threaded and suited for applications requiring precise thread engagement. Machinists, millwrights, and maintenance technicians install this type of fastener when torque retention and material strength are critical requirements.

This hex socket cap screw is used across a wide range of industrial and mechanical applications including machine frames, fixtures, tooling plates, and structural steel assemblies. The 1-8 UNC thread designation is a coarse-thread standard common in general industrial fastening where vibration resistance and ease of assembly are priorities. The alloy steel construction supports higher clamping loads compared to standard steel fasteners, making it appropriate for heavy-duty or high-cycle service environments.

Key Features

• 1-8 UNC coarse thread for broad industrial fastening compatibility
• 3.5-inch length under head for deep engagement in thick materials
• Alloy steel construction for high tensile strength and clamping force
• Black oxide finish provides mild corrosion resistance and reduces light glare
• Partial threading allows for shank grip in clearance-hole applications
• 3/4-inch hex drive for use with standard hex keys and socket drive tools

Compatibility

Designed as a standard 1-8 UNC hex socket cap screw for use in applications requiring a 3.5-inch partially threaded alloy steel fastener with a 3/4-inch hex drive.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a 3/4-inch hex key or socket driver. Ensure mating threads are clean and free of debris before installation. Apply thread lubricant or thread-locking compound as required by the application specification. Follow applicable torque specifications from engineering documentation or fastener manufacturer guidelines for the alloy steel grade in use.
