Value Collection 581840BR Hex Socket Cap Screw 1-14 Unf

Product Description

The VALUE COLLECTION 581840BR is a fully threaded hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling fixtures, and structural connections. Manufactured from alloy steel with a black oxide coating, it meets ASME/ANSI B18.3 and ASTM A574 standards, confirming compliance with recognized dimensional and mechanical property requirements. The screw uses a 3/4 inch hex drive and measures 3.25 inches under the head, making it suitable for applications requiring a longer grip in tight-clearance bores. The 1-14 UNF thread form provides fine-pitch engagement for improved thread strength and vibration resistance compared to coarse-thread equivalents.

This cap screw is used across industrial, manufacturing, and maintenance applications where alloy steel strength and a clean, low-profile socket head are required. Typical installations include machine bases, hydraulic component mounting, press tooling, and equipment frames. The black oxide finish provides mild corrosion resistance and reduces light reflection, making it a practical choice in both indoor industrial and controlled-environment settings. Machinists, millwrights, and maintenance mechanics routinely specify this thread size and drive configuration for medium-to-heavy duty bolted joints.

Key Features

• 1-14 UNF fine thread for higher thread engagement strength and vibration resistance
• 3.25 inch length under head accommodates deeper grip requirements
• 3/4 inch internal hex drive allows high torque input with standard Allen or hex key tooling
• Alloy steel construction meets ASTM A574 mechanical requirements
• Black oxide coating provides mild corrosion resistance and a non-reflective finish
• Fully threaded shank maximizes engagement along the entire fastener length

Compatibility

Designed as an OEM-style or replacement fastener for any assembly specifying a 1-14 UNF fully threaded socket head cap screw conforming to ASME/ANSI B18.3 and ASTM A574 standards.

Installation Notes

Installation should be performed by a qualified mechanic or millwright using a calibrated torque wrench and the appropriate 3/4 inch hex key or socket drive. Ensure the mating threaded hole is clean, undamaged, and of compatible thread class before installation. De-energize and lock out any equipment before fastener service per applicable OSHA lockout/tagout procedures. Do not exceed the rated torque for the fastener grade as specified in ASME or ASTM reference tables for ASTM A574 alloy steel socket head cap screws.
