The HOLO-KROME 04050 is a spiral vent pull out dowel pin designed for precision fastening applications in industrial and mechanical assembly work. Manufactured from Grade 4000 alloy steel with a black luster finish, this pin measures 3/8 inch in diameter and 2 inches in overall length. The threaded end type allows for controlled extraction using a standard pull out tool, making it suitable for applications where disassembly is required. Surface hardness is rated at Rockwell C60-64 and core hardness at Rockwell C50-58, providing the wear resistance and shear strength that mechanical assembly technicians and maintenance professionals depend on in demanding service conditions.
This dowel pin is appropriate for use in manufacturing, tooling, fixture building, and mechanical assembly environments where precise alignment and secure positioning of mating components is critical. The spiral vent design allows air and fluid to escape during press-fit installation, reducing hydraulic lock and installation force. It is typically installed by machinists, millwrights, and maintenance technicians working on jigs, dies, molds, and precision machine components.
Designed as a standard OEM-style replacement or new-installation spiral vent pull out dowel pin conforming to ASME/ANSI B18.8.2 and MIL-S-7742 specifications, suitable for any application requiring a 3/8-inch diameter threaded-end dowel pin.
Installation is performed by machinists or maintenance technicians using a hydraulic or mechanical press. Ensure mating holes are reamed to the appropriate tolerance before installation to achieve proper fit. Do not hammer the pin directly without a proper driver to avoid damaging the threaded end. Always verify hole depth and alignment before pressing the pin to its final seated position.
