Holo-krome 02101 Pull Out Dowel Pin 10x70mm Grade 8

Product Description

The HOLO-KROME 02101 is a standard pull out dowel pin machined from Grade 8 alloy steel and finished in black luster. It measures 10 mm in diameter and 70 mm in overall length, with one beveled end and one rounded end to aid alignment and installation. The pull out design includes a threaded or recessed extraction feature that allows the pin to be removed cleanly from blind-hole applications without damaging the surrounding bore. It conforms to ASME B18.8.5M and is suited for precision alignment and locating work in mechanical assemblies. Licensed trades and machine shop professionals install this type of pin in production fixtures, jigs, and structural assemblies where repeatable part positioning is required.

This dowel pin is used in industrial and manufacturing environments where tight-tolerance locating is critical. Typical applications include fixture plates, die sets, mold assemblies, and machine frames where components must be accurately and repeatedly aligned. The Grade 8 alloy steel construction provides the hardness and shear strength needed for high-load locating duty. The black luster finish offers mild corrosion resistance for shop-floor storage and service conditions.

Key Features

• 10 mm diameter with diameter tolerance of -0.0001 to 0.0001 inches for precise bore fit
• 70 mm overall length suits moderate-depth locating and alignment applications
• One beveled end and one rounded end for guided insertion and extraction
• Pull out design allows clean removal from blind holes without bore damage
• Grade 8 alloy steel provides high shear strength and hardness
• Conforms to ASME B18.8.5M for standardized fitment and interchangeability

Compatibility

Designed as an OEM-style replacement or standard component for mechanical assemblies, jigs, fixtures, and locating applications requiring ASME B18.8.5M compliant pull out dowel pins in 10 mm diameter.

Installation Notes

Pull out dowel pins are typically installed by machinists or millwrights using a press or mallet after boring the receiving hole to the proper tolerance. Ensure the mating bore is clean, deburred, and dimensionally verified before pressing the pin. Do not hammer directly on the pin face without a proper driver to avoid deforming the end geometry. Use the extraction feature with the appropriate puller tool to remove the pin without reaming or damaging the bore.
