Midwest Fasteners 60871 5/16"-24 x 5/16" Black Oxide Steel Socket Set Screw

The Midwest Fasteners 60871 is a 5/16"-24 x 5/16" socket set screw machined from steel and finished in black oxide for a durable, low-glare surface. Built on a fine thread pitch, this set screw is designed to seat securely into tapped holes for locking collars, pulleys, gears and other rotating components in place on a shaft. Each unit ships individually (Package: Each), making it easy to source the exact quantity needed for a repair or production run without buying an oversized assortment box.

Key Features

• Size: 5/16"-24 thread x 5/16" length, matching the stated 5/16" product size for a precise fit in tapped mounting holes.
• Material & Finish: Steel construction with a black oxide finish for a tough, mildly corrosion-resistant surface and a uniform black appearance.
• Thread: Fine thread (5/16"-24) for finer adjustment and increased resistance to loosening under vibration compared to coarse thread alternatives.
• Drive Style: Socket (hex socket) head, allowing the screw to seat flush or below the surface while still providing strong torque transfer with an Allen-style wrench.
• Color: Black, consistent with the black oxide finish, for a clean, non-reflective look on exposed assemblies.
• Package: Each - sold individually so you can match quantity to your job.
