Value Collection 34912 Pull Out Dowel Pin 1/2x1 in Alloy Steel

Product Description

The VALUE COLLECTION 34912 is a standard pull out dowel pin designed for precision alignment and locating applications in mechanical assemblies. Manufactured from alloy steel to Material Grade 8, this pin meets ASME B18.8.2 dimensional standards and delivers a Rockwell hardness of C 50-58, providing reliable resistance to wear and deformation under load. The pin measures 1/2 inch in diameter with an overall length of 1 inch. Diameter tolerance is held to 0.0002 inches, ensuring consistent fit in close-tolerance bored holes. One end is beveled for easy insertion; the opposite end is rounded to facilitate pull-out removal. Licensed HVAC techs, machinists, millwrights, and maintenance technicians working on precision equipment routinely use this type of pin.

This dowel pin is suited for use in jigs, fixtures, dies, and mechanical assemblies where accurate part alignment is critical. The pull-out style is particularly useful in blind-hole applications where standard press-fit dowels cannot be driven out from the opposite side. Sold in a package quantity of 10, this pin is a practical stocking item for tool rooms, maintenance departments, and fabrication shops handling repetitive alignment tasks.

Key Features

• Alloy steel construction, Material Grade 8 for high strength and wear resistance
• Rockwell hardness C 50-58 for dimensional stability under load
• Diameter tolerance of 0.0002 inches for precise close-tolerance fit
• One beveled end for guided insertion, one rounded end for pull-out removal
• Meets ASME B18.8.2 fastener standard
• Rated for double shear breaking strength measurement

Compatibility

Designed as an OEM-style replacement or stocking component for standard pull-out dowel pin applications in mechanical assemblies conforming to ASME B18.8.2.

Installation Notes

Installation and removal should be performed by a qualified machinist or maintenance technician familiar with precision fastener practices. Power down and de-energize all equipment before servicing assemblies containing dowel pins. Use appropriate insertion and extraction tooling sized for 1/2 inch diameter pins to avoid damaging hole bores or pin geometry. Do not use a hammer directly on the rounded pull-out end, as this can deform the extraction surface.
