Value Collection 606093PR Set Screw 5-40 X 1/4 in Half Dog

Product Description

The VALUE COLLECTION 606093PR is a 5-40 UNC alloy steel set screw with a half dog point, designed for precision fastening applications in mechanical assemblies. Measuring 1/4 inch in overall length, it is driven by a 1/16 inch hex key and meets ASME/ANSI B18.3 and ASTM F912 standards. The Grade 8 alloy steel construction provides high tensile strength and hardness suitable for demanding clamping and positioning tasks. This fastener is typically installed by machinists, millwrights, and maintenance technicians working on shafts, collars, and mechanical components requiring secure, adjustable locking.

The 606093PR is suited for use in industrial and mechanical assembly environments where a half dog point is needed to engage a mating hole or recess for positive location without marring the shaft surface. The fine 5-40 thread pitch allows for controlled torque application in small-bore or close-tolerance assemblies. This screw is commonly specified in light machine tool components, instrumentation, and precision shaft collar applications.

Key Features

• Half dog point engages mating holes or recesses for positive shaft location
• Grade 8 alloy steel construction for high tensile strength and hardness
• 5-40 UNC thread standard for fine, controlled engagement
• 1/16 inch internal hex drive for use with standard hex keys in tight spaces
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• 1/4 inch overall length suitable for thin collars and shallow bore applications

Compatibility

Designed as an OEM-style replacement or standard stock fastener for mechanical assemblies requiring a 5-40 UNC half dog point set screw with a 1/16 inch hex drive.

Installation Notes

Installation is performed by machinists or maintenance technicians using a 1/16 inch hex key. Always ensure the mating assembly is de-energized and stationary before fastener installation or removal. Engage the hex drive fully to avoid cam-out and fastener damage. Torque to the assembly manufacturer's specification for the thread size and grade.
