Value Collection 40124 Pull Out Dowel Pin 0.5x4 in Alloy Steel

Product Description

The VALUE COLLECTION 40124 is a standard pull out dowel pin used for precise alignment and location of mating components in mechanical assemblies. Manufactured from Grade 8 alloy steel with a bright finish, this pin measures 0.5 inches in diameter and 4 inches in overall length. It conforms to ASME B18.8.2 and delivers a single shear strength of 29,450 pounds and a double shear strength of 58,900 pounds. One end is beveled and one end is rounded, which aids in insertion and pull-out during maintenance operations. Machinists, toolmakers, and mechanical assembly technicians are the primary installers.

This dowel pin is suited for jig and fixture work, die sets, mold alignment, and general precision machining applications where repeatable component positioning is required. The 0.5-inch diameter and 4-inch length make it appropriate for medium-duty structural alignment tasks in both production and toolroom environments. The diameter tolerance of 0.0002 inches ensures a controlled fit in reamed holes per ASME B18.8.2 requirements. Sold in packages of 10 with a minimum order quantity of 1 package.

Key Features

• Grade 8 alloy steel construction provides high shear strength for demanding alignment applications
• Single shear strength of 29,450 pounds and double shear strength of 58,900 pounds
• Diameter tolerance of 0.0002 inches for precision fit in reamed holes
• One beveled end and one rounded end for easier insertion and removal
• Bright finish for corrosion resistance in typical shop environments
• Conforms to ASME B18.8.2 fastener standard

Compatibility

Designed as an ASME B18.8.2-compliant pull out dowel pin for use in reamed holes requiring a 0.5-inch nominal diameter in precision mechanical assemblies, dies, molds, and fixtures.

Installation Notes

Installation is typically performed by machinists or toolmakers using a press or mallet with a suitable driver. The receiving hole should be finish-reamed to the correct tolerance before pin insertion. Always de-energize or lock out any machine before servicing components that use dowel pins for alignment. Do not force pins into undersized holes, as this may compromise the dimensional integrity of the bore or the pin itself.
