[100 PKG] Set Screws Socket Cup Point Nylon Patch Alloy Thermal Black Oxide 1/4-20 X 1 1/4

Set Screws Socket Cup Point Nylon Patch Alloy Thermal Black Oxide 1/4-20 X 1 1/4 is a precision fastener engineered for secure, vibration-resistant clamping in mechanical assemblies.

Featuring a socket drive for easy installation, a cup point that bites into soft materials for enhanced grip, and a nylon patch that reduces surface marring while helping prevent loosening under vibration, this fastener is built to perform where reliability matters.

• Thread size & length: 1/4-20 UNC, 1 1/4" long.
• Drive: Internal hex (socket) drive for a flush, low-profile head.
• Head style: Cup point for secure seating and clamping force distribution.
• Material & finish: Alloy steel with a nylon patch and a thermally applied black oxide finish for wear resistance and reduced glare.
• Applications: Ideal for fastener applications in machinery, automotive, electronics enclosures, and equipment where a positive, non-marring grip is required.

Why choose this set screw? It combines robust alloy strength with a nylon patch to protect mating surfaces, while the black oxide finish enhances durability and corrosion resistance. The cup point design provides a secure grip in soft substrates, preventing loosening and reducing vibration-induced movement.
