Holo-krome 78014 Hex Socket Cap Screw 4-40 Unc Stainless

Product Description

The HOLO-KROME 78014 is a hex socket cap screw designed for secure, high-torque fastening in tight spaces where a standard hex head wrench cannot reach. Sized at 4-40 UNC thread with a 1/2 inch length under the head, this fastener accepts a 3/32 inch hex drive. It is manufactured from 18-8 stainless steel with a bright, uncoated finish, providing corrosion resistance suitable for both indoor and outdoor applications. The fully threaded shank delivers maximum thread engagement across the entire grip length. This screw meets ASME B18.3 and ASTM F837 standards and is a common choice for precision assemblies, instrumentation, and mechanical sub-assemblies worked on by machinists, maintenance technicians, and field service professionals.

The HOLO-KROME 78014 is used in applications requiring a compact, flush or low-profile fastener with reliable clamping force. Typical installation scenarios include light structural assemblies, electronic enclosures, HVAC controls, electrical panels, and precision mechanical components where thread size 4-40 UNC is specified. The fine 4-40 thread pitch is well suited to thin-material fastening and applications where vibration resistance and controlled torque are priorities. This screw is appropriate for both residential and commercial service environments wherever stainless steel corrosion resistance is required.

Key Features

• 4-40 UNC thread for compatibility with fine-threaded tapped holes in light-gauge and precision assemblies
• 1/2 inch length under head provides adequate grip for standard panel and bracket thickness
• 3/32 inch hex socket drive allows installation with a standard Allen wrench or hex bit driver
• 18-8 stainless steel construction resists corrosion in wet or humid environments
• Fully threaded shank maximizes thread engagement for secure fastening
• Meets ASME B18.3 and ASTM F837 dimensional and mechanical standards

Compatibility

Designed as a standard 4-40 UNC hex socket cap screw for use in any tapped hole or threaded insert conforming to 4-40 UNC thread specifications per ASME B18.3.

Installation Notes

Installation requires a 3/32 inch hex key or Allen driver. Ensure the mating tapped hole is clean and free of debris before driving the screw. Avoid over-torquing into thin or soft base materials, as the 4-40 thread form is susceptible to strip-out under excessive load. Follow applicable mechanical or electrical assembly codes and manufacturer torque guidelines for the host assembly.
