UN Replacement Jaw Set for Cast Iron and Steel Vises (model BY MCX)

UN Replacement Jaw Set for Cast Iron and Steel Vises (model BY MCX) provides a direct-fit spare set of jaws engineered to restore or upgrade clamping surfaces on compatible bench vises. Designed for use with cast iron and steel vises, the jaw faces create flat, secure contact points for holding metal parts, bars and other workpieces during machining, filing, drilling or assembly operations. The set is intended as a maintenance component to replace worn, damaged or missing jaws and returns the vise to reliable, repeatable clamping performance.

Advantages

The replacement jaws are manufactured to match the profile and thickness required for many cast iron and steel bench vises, ensuring even pressure distribution and secure grip. Their durable construction resists deformation under normal workshop loads and supports precise alignment of workpieces. As a direct-replacement spare, the set simplifies maintenance by eliminating the need for machining or makeshift jaw repairs, reducing downtime and extending the service life of the vise.

Suitable for

• Repairing or refurbishing cast iron bench vises
• Replacing worn or damaged jaws on steel vises
• General metalworking tasks such as drilling, filing and grinding
• Workshop maintenance and preventive replacement of clamping surfaces

Key specifications

• Compatibility: designed for use with cast iron and steel bench vises
• Material: engineered for durable clamping contact and resistance to workshop loads
• Design: flat jaw faces suitable for holding metal workpieces and general-purpose clamping
• Fit: direct-replacement geometry to restore original vise clamping surfaces

How to use

Remove the existing jaws from the vise following the manufacturer’s instructions or by loosening the mounting bolts or pins that secure the jaw faces. Position the replacement jaw set so that the bolt holes and alignment features match the vise body, then fasten securely with appropriate hardware. Verify that the jaws are parallel and the clamping surfaces engage evenly. After installation, perform a test clamp on a scrap workpiece to confirm grip and alignment before resuming regular tasks.

Usage recommendations

Use the replacement jaws with appropriate tightening torque to avoid damaging the mounting threads or deforming the jaw faces; inspect periodically for wear and replace when contact surfaces show excessive scoring, galling, or deformation.
