Value Collection SF043011 Dowel Pin 12x40mm Alloy Steel

Product Description

The VALUE COLLECTION SF043011 is a flat vent pull out dowel pin manufactured from alloy steel to DIN 7979D standards. At 12 mm in diameter and 40 mm in overall length, this pin is designed for precision locating applications in tooling, fixtures, and machine assemblies. One end is rounded for guided insertion, while the opposite end is threaded to allow mechanical extraction without damage to the bore. Hardness is rated at 57-63 HRC, providing the wear resistance required in high-cycle or heavy-load locating scenarios. Machinists, toolmakers, and maintenance technicians install this type of pin in production and MRO environments.

This dowel pin suits applications where a standard press-fit pin is not acceptable because the part must be removable without specialized removal tooling. The flat vent feature allows trapped air and lubricants to escape during installation, reducing hydraulic lock in blind bores. Typical installations include jigs, dies, mold bases, and machine tool fixtures where repeatable, high-precision alignment of mated components is critical. The threaded extraction end simplifies scheduled maintenance and component changeover.

Key Features

• Flat vent design prevents hydraulic lock in blind-bore installations
• Threaded extraction end enables clean removal without bore damage
• 57-63 HRC hardness for wear-resistant precision locating duty
• Conforms to DIN 7979D standard for interchangeable fitment
• Alloy steel construction supports high-load and high-cycle applications

Compatibility

Designed as a DIN 7979D-compliant flat vent pull out dowel pin for use in jigs, fixtures, dies, mold bases, and machine tool assemblies requiring a removable precision locating pin in a 12 mm bore diameter.

Installation Notes

Installation and removal should be performed by a qualified machinist or maintenance technician familiar with precision fastener practices. Confirm bore diameter and tolerance before pressing the pin to avoid galling or bore damage. Always de-energize and lock out the machine before servicing fixtures or tooling that contain locating pins. Use the threaded end with an appropriate extraction tool or slide hammer adapter for removal; do not drive the pin from the threaded end.
