Value Collection C703503 Hex Head Cap Screw 3/4-16

Product Description

The VALUE COLLECTION C703503 is a 3/4-16 hex head cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Manufactured from Grade 8 steel and left uncoated, this fully threaded fastener meets ASME B18.2.1 dimensional standards. The 3/4-16 thread designation indicates a 3/4-inch nominal diameter with a 16-thread-per-inch Unified National Fine (UNF) pitch, providing strong clamping force and resistance to loosening under vibration. The 1-1/4-inch length is measured under the head. This fastener is sold in a package of 25 units and is appropriate for use by millwrights, maintenance mechanics, pipefitters, and general industrial technicians requiring a reliable, spec-compliant Grade 8 fastener.

Grade 8 hex head cap screws are commonly used in high-load mechanical joints, equipment mounting, flanged connections, and structural steel assemblies where tensile strength requirements exceed what Grade 5 or lower fasteners can provide. The fully threaded configuration allows maximum thread engagement across the full 1-1/4-inch length, making this screw well suited for through-bolt applications and joints requiring even clamping distribution. This screw is appropriate for both OEM assembly and field maintenance use across manufacturing, HVAC equipment mounting, and industrial machinery applications.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• 3/4-16 UNF thread for fine-pitch engagement and vibration resistance
• Fully threaded along the full 1-1/4-inch length under head
• Meets ASME B18.2.1 dimensional standard for hex head cap screws
• Uncoated finish suitable for use with custom coatings or dry applications
• Sold in a package of 25 units

Compatibility

Designed as a standard ASME B18.2.1-compliant Grade 8 hex head cap screw suitable for any application requiring a 3/4-16 UNF fully threaded fastener with a 1-1/4-inch length under head.

Installation Notes

Installation should be performed by a qualified mechanic or technician familiar with fastener torque requirements for Grade 8 hardware. Always consult applicable engineering specifications or fastener torque charts for the correct tightening value based on joint material and lubrication conditions. Use a properly sized hex wrench or socket to avoid rounding the head. Inspect threads for damage before installation and ensure mating threads are clean and free of debris.
