Value Collection 548608BR Dowel Pin 16x40mm Alloy Steel

Product Description

The VALUE COLLECTION 548608BR is a flat vent pull out dowel pin designed for precision location and alignment in machined assemblies. Manufactured from alloy steel to DIN 7979D, this pin measures 16 mm in diameter and 40 mm in overall length, with a hardness rating of 57-63 HRC for reliable wear resistance under load. One end is rounded for guided insertion and the other end is threaded to allow controlled extraction from blind holes using a standard pull-out tool. Machinists, toolmakers, and maintenance technicians install this pin where repeatable part registration is required in dies, fixtures, and machined components.

This dowel pin is suited for industrial and manufacturing applications where tight-tolerance location between mating components is critical. The flat vent channel along the pin body allows trapped air and excess lubricant to escape during press-fit installation, reducing hydraulic lock and preventing bore damage. It is appropriate for use in press-fit or slip-fit bored holes in tooling plates, jigs, fixtures, and precision assemblies across light and heavy manufacturing environments.

Key Features

• Flat vent design allows air and lubricant to escape during installation, preventing hydraulic lock
• Threaded end enables controlled extraction from blind holes without bore damage
• Alloy steel construction with 57-63 HRC hardness for durability under cyclic loading
• Conforms to DIN 7979D fastener standard for dimensional consistency
• 16 mm diameter x 40 mm length suits common tooling and fixture bore sizes

Compatibility

Designed as a DIN 7979D-compliant flat vent pull out dowel pin for use in precision-bored holes in machined tooling, fixtures, jigs, and industrial assemblies requiring a 16 mm nominal diameter locating pin.

Installation Notes

Installation is typically performed by toolmakers or machinist technicians using an arbor press or hydraulic press. The mating bore should be finished to the tolerance specified by DIN 7979D for the intended fit class before installation. Ensure the bore and pin are clean and lightly lubricated prior to pressing. Use the threaded extraction end with an appropriate pull-out tool for removal to avoid bore galling or pin damage.
