Value Collection 706375PR Set Screw 1/4-20 X 3/4 in Half Dog

Product Description

The VALUE COLLECTION 706375PR is a 1/4-20 x 3/4-inch half dog point set screw manufactured from austenitic Grade A2 stainless steel. It is driven with a 1/8-inch hex key and conforms to ASME/ANSI B18.3 and ASTM F880 standards. The half dog point provides a short cylindrical pilot that seats into a mating hole or groove, holding shafts, collars, and other components securely against rotational or axial movement. This screw is suited for applications where corrosion resistance and dimensional precision are required. Machinists, maintenance technicians, and assembly professionals install this fastener in light-to-medium duty mechanical assemblies.

This set screw is used in shaft-to-hub connections, shaft collars, couplings, and similar mechanical assemblies where a non-protruding fastener is required. The half dog point is particularly effective when a locating or locking function is needed in a pre-drilled or bored hole on a mating component. Its stainless steel construction makes it appropriate for environments with moisture exposure or mild chemical contact, including food processing equipment, marine hardware, and general industrial machinery.

Key Features

• Half dog point provides a short cylindrical pilot for positive location in mating holes or slots
• Austenitic Grade A2 stainless steel offers corrosion resistance in wet and mildly corrosive environments
• 1/4-20 UNC threading for compatibility with standard inch-series tapped holes
• 1/8-inch hex drive allows installation with a standard hex key or Allen wrench
• Meets ASME/ANSI B18.3 and ASTM F880 dimensional and material standards
• Headless design sits flush or below the surface, eliminating protrusions on rotating parts

Compatibility

Designed as a standard 1/4-20 UNC inch-series set screw for use in any tapped hole conforming to 1/4-20 thread specifications requiring a half dog point style fastener.

Installation Notes

Installation is performed with a 1/8-inch hex key; ensure the key is fully seated before applying torque to avoid rounding the socket. Power down and de-energize any equipment before accessing shaft assemblies or rotating components. Follow applicable machine guarding and lockout/tagout procedures per OSHA and equipment manufacturer guidelines. Do not over-tighten stainless steel fasteners, as galling can occur; applying an appropriate anti-seize compound is common practice with stainless set screws.
