Value Collection -48549-4 Hex Socket Cap Screw 3/4-16 Unf

Product Description

The VALUE COLLECTION -48549-4 is a fully threaded hex socket cap screw designed for high-strength bolted connections in mechanical, industrial, and trade applications. Manufactured from alloy steel and finished with a black oxide coating, this fastener delivers corrosion resistance and reduced light glare in demanding environments. It features a 3/4-16 UNF thread size, a 1-3/4-inch length under head, and a 5/8-inch hex drive. The combination of alloy steel construction and black oxide finish meets ASME/ANSI B18.3 and ASTM A574 standards, making it a reliable choice for load-bearing assemblies where dimensional precision and material integrity are required.

This hex socket cap screw is suited for use in general industrial machinery, equipment assembly, structural fastening, and maintenance applications across multiple trades. The 3/4-16 UNF thread pitch is a fine-thread configuration, preferred where vibration resistance or fine adjustment is needed. The 5/8-inch hex drive accepts a standard hex key or Allen wrench, allowing installation in recessed or tight-clearance locations where a conventional bolt head would not fit. The black oxide finish is appropriate for indoor or protected environments where moderate corrosion resistance is acceptable.

Key Features

• 3/4-16 UNF fine-thread configuration for vibration-resistant fastening
• 1-3/4-inch length under head, fully threaded for maximum thread engagement
• 5/8-inch hex socket drive for use with hex keys in tight or recessed spaces
• Alloy steel construction meets ASTM A574 strength requirements
• Black oxide coating provides moderate corrosion resistance and low-reflectance finish
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as an OEM-style replacement or standard-service fastener compatible with any application requiring a 3/4-16 UNF fully threaded hex socket cap screw meeting ASME/ANSI B18.3 and ASTM A574 specifications.

Installation Notes

Installation is typically performed by mechanical technicians, millwrights, or trade professionals using a calibrated torque wrench and the appropriate 5/8-inch hex key or bit. Always de-energize and lock out equipment before accessing fastened assemblies per applicable safety procedures. Do not exceed torque values specified by the equipment manufacturer for this thread size and grade. Black oxide finished fasteners are best suited for dry or lightly oiled environments and should not be substituted for stainless or plated fasteners in high-moisture or outdoor exposure applications without engineering review.
