Value Collection R63642484 Set Screw 5/16-18 X 3/4 in Brass

Product Description

The VALUE COLLECTION R63642484 is a brass cup point set screw designed for mechanical fastening applications where a secure, non-permanent hold is required. Threaded 5/16-18 UNC with an overall length of 3/4 inches, this set screw is driven by a 5/32-inch hex key and seats firmly via its cup point tip, which bites into the mating shaft surface to resist rotation and axial movement. Brass construction provides corrosion resistance and is well-suited for use in environments where galling or spark risk makes steel fasteners less appropriate. Installed by machinists, millwrights, and maintenance technicians across a wide range of industries.

This set screw is used in collars, pulleys, gears, knobs, and similar components where the fastener must clamp a part to a shaft without protruding above the surface. The cup point geometry is one of the most common point styles for general-purpose holding power. Typical applications include light machinery, instrumentation, HVAC equipment assemblies, and plumbing fixture components. This item is sold individually but carries a minimum order quantity of 10 pieces.

Key Features

• 5/16-18 UNC thread size for compatibility with standard inch-series tapped holes
• 3/4-inch overall length suits moderate-depth clamping requirements
• Cup point tip bites into shaft surface for reliable holding without a protruding head
• 5/32-inch hex drive accepts standard hex keys and Allen wrenches
• Brass material resists corrosion and reduces galling risk on softer shaft materials
• Headless profile allows flush or below-surface installation

Compatibility

Designed as a standard 5/16-18 UNC cup point set screw suitable for any tapped hole or collar machined to that thread specification in inch-series applications.

Installation Notes

Installation requires a 5/32-inch hex key or T-handle Allen wrench. Ensure the mating component is clean and the tapped hole is free of debris before threading the screw. Power down or de-energize any equipment before accessing rotating components such as pulleys or collars. Do not overtighten brass fasteners, as the material is softer than steel and the threads can strip under excessive torque.
