Precision Brand 04035 Square Key Stock 12 in 4 Piece

Product Description

The PRECISION BRAND 04035 is a square key stock used to secure rotating components such as gears, pulleys, and sprockets to shafts in mechanical power transmission assemblies. Each piece measures 12 inches in length with a 10 mm square cross-section, conforming to DIN 6880 material specification. Manufactured from low-carbon steel with a gold dichromate finish, this key stock resists corrosion while maintaining the dimensional consistency required for reliable keyway fits. Each package contains 4 pieces. Machinists, millwrights, and maintenance technicians working on drive systems and rotating equipment are the primary installers of this hardware.

Square key stock in this size range is commonly used in industrial and light commercial mechanical assemblies where a positive drive connection between a shaft and a hub component is required. The 10 mm square profile suits metric-dimensioned keyways per DIN standards, making it appropriate for equipment sourced or designed to metric specifications. Technicians typically cut pieces to the required length with a hacksaw or cold saw before fitting them into the keyway. This product is sold in a 4-piece pack with a minimum order quantity of 1 pack.

Installation Notes

Installation is typically performed by machinists or millwrights during equipment assembly or shaft repair. Always de-energize and lock out the machine before removing or installing key stock. Cut key stock to length using appropriate metal-cutting tools and deburr all edges before fitting. Ensure the keyway and key stock dimensions are within tolerance before pressing or driving the key into position to avoid damage to the shaft or hub.
