Value Collection A996665 Dowel Pin 16x40mm Alloy Steel

Product Description

The VALUE COLLECTION A996665 is a flat vent pull out dowel pin used for precision alignment and fixturing in mechanical assemblies. Manufactured from alloy steel, this pin meets DIN 7979D standards and carries a Rockwell hardness rating of C 57-63, making it suitable for applications that require a hard, wear-resistant locating pin. The 16 mm diameter and 40 mm overall length provide a robust footprint for heavy-duty tooling, jig, and fixture work. One end is rounded and the other end is threaded, which allows the pin to be pulled out of a blind hole using a standard extraction tool. Machinists, toolmakers, and maintenance technicians typically install this type of pin in production tooling and machine fixturing.

This dowel pin is commonly used in industrial manufacturing environments where repeatable, accurate part location is required. Flat vent pull out designs are specified when a pin must be installed in a blind bore and later removed without damaging the surrounding material. The flat vent groove allows trapped air and lubricant to escape during press installation, reducing hydraulic lock. The threaded end accepts a puller or extraction bolt for controlled removal. Typical applications include die sets, jigs, fixtures, and machine tool assemblies where alloy steel hardness and DIN dimensional compliance are required.

Key Features

• DIN 7979D compliant for standardized interchangeability in tooling applications
• Alloy steel construction with C 57-63 Rockwell hardness for wear resistance
• Flat vent groove allows air and lubricant to escape during blind-bore installation
• One rounded end for guided insertion and one threaded end for mechanical extraction
• 16 mm diameter x 40 mm overall length for heavy-duty fixturing fitment

Compatibility

Designed as a DIN 7979D-compliant flat vent pull out dowel pin for use in industrial jigs, fixtures, die sets, and machine tool assemblies requiring a 16 mm diameter locating pin.

Installation Notes

Installation and removal should be performed by a qualified machinist or maintenance technician familiar with precision dowel pin practices. Press the pin into the bored hole using an arbor press or suitable driving tool, ensuring the bore diameter conforms to DIN 7979D tolerance specifications for the 16 mm nominal size. The flat vent groove must be oriented to allow trapped air to escape during pressing. To remove, thread an appropriate extraction bolt into the threaded end and use a standard slide hammer or puller to draw the pin out without side-loading the bore.
