Value Collection R63642924 Set Screw 1/4-20 X 3/4 in Cup Point Brass

Product Description

The VALUE COLLECTION R63642924 is a 1/4-20 UNC cup point set screw machined from brass. At 3/4 inches in overall length, it is driven by a 1/8-inch hex key and seats against a shaft or mating surface using its cup point tip to resist rotational and axial movement. Brass construction offers corrosion resistance and is well suited for applications requiring non-magnetic or non-sparking fastener properties. This screw ships individually but carries a minimum order quantity of 10 units. It is a standard stock item for maintenance, repair, and light fabrication work across mechanical and trade applications.

Cup point set screws in this size range are commonly used to lock collars, pulleys, gears, and shaft-mounted components in place. The 1/4-20 UNC thread is one of the most widely used coarse-thread sizes in North American hardware, making this screw a frequent go-to for equipment assembly and field repair in HVAC, electrical, plumbing, and general mechanical service. Brass is often selected where steel screws could cause galvanic corrosion or where a softer material is needed to avoid damaging a shaft surface.

Key Features

• 1/4-20 UNC coarse thread for broad hardware compatibility
• Cup point tip grips shaft surfaces to resist movement under load
• Brass material provides corrosion resistance and non-magnetic properties
• 1/8-inch hex drive accepts standard hex keys and Allen wrenches
• 3/4-inch overall length suits medium-depth collar and hub applications

Compatibility

Designed as a standard 1/4-20 UNC cup point set screw suitable for use in any application accepting this thread size, drive type, and overall length.

Installation Notes

Set screws of this type are installed by machinists, maintenance technicians, and trade professionals using a 1/8-inch hex key. Ensure the mating threaded hole is clean and free of debris before installation. Do not over-torque brass fasteners, as the material is softer than steel and threads can strip under excessive force. Confirm the shaft or mating surface is secure before returning equipment to service.
