Holo-krome 01134 Dowel Pin 1/2x2 in Alloy Steel Grade 8

Product Description

The HOLO-KROME 01134 is a standard dowel pin used to align, locate, and retain mating components in mechanical assemblies. Manufactured from Grade 8 alloy steel with a black luster finish, it delivers high shear strength and surface hardness suited for precision fastening applications. The pin measures 0.5 inches in diameter and 2 inches in overall length, with a diameter tolerance of -0.0001 to 0.0001 inches for tight, repeatable fits. One end is beveled and the other is rounded, making installation and press-fit seating straightforward. Machinists, maintenance technicians, and mechanical assemblers install this pin in tooling fixtures, jigs, and production machinery where accurate component registration is required.

This dowel pin is suited for use in industrial and manufacturing environments wherever precise hole-to-hole alignment is needed between two or more workpieces. Typical applications include die sets, mold bases, machine frames, and fabricated assemblies requiring consistent, repeatable positioning. The alloy steel construction and black luster surface coating make it appropriate for use in both shop-floor tooling and light structural applications where corrosion resistance is a secondary concern and mechanical strength is the priority.

Key Features

• Grade 8 alloy steel construction for high shear and tensile strength
• Black luster finish for mild surface protection and visual identification
• Diameter tolerance of -0.0001 to 0.0001 inches for precision press-fit applications
• One beveled end and one rounded end to aid alignment and installation
• Conforms to ASME B18.8.2 standard for dimensional and geometric consistency
• 0.5-inch diameter by 2-inch length for medium-duty alignment tasks

Compatibility

Designed as an OEM-style replacement or direct-use standard dowel pin for mechanical assemblies requiring ASME B18.8.2 compliant 1/2-inch diameter locating pins.

Installation Notes

Installation is typically performed by machinists or mechanical assemblers using an arbor press or soft-faced mallet to seat the pin into a reamed or precision-drilled hole. De-energize and lock out all machinery before servicing any assembly containing dowel pins. Holes should be reamed to the appropriate tolerance class before installation to ensure the intended fit; never force a pin into an undersized hole with excessive impact. Follow applicable shop safety procedures and relevant ASME or OSHA guidelines when working with press-fit fasteners.
