The Yost SD-400C 4 Inch Mechanics Bench Vise is a highly durable, high-strength-to-weight ratio combination vise designed for the serious DIY enthusiast or small workshop. Built with an emphasis on both power and maneuverability, this vise is perfectly suited for a wide range of repair, fabrication, and clamping tasks.

Constructed from robust 70,000 psi ductile iron, the vise is engineered to generate impressive clamping force while remaining relatively lightweight. This strength is maximized by the straight-pull screw and nut design, ensuring secure and reliable holding power. The Yost SD-400C is highly versatile, featuring replaceable pipe jaws that securely grip round stock from 1/8" to 2.5" in diameter. An interlocking swivel base allows you to adjust the working angle of your piece and lock it firmly in place, while the generous anvil work surface provides a sturdy, flat area for hammering, shaping, and light fabrication. With a 4" jaw width and 4.5" maximum jaw opening, this vise is an essential tool for any workbench, ready to handle small to medium-sized projects with professional-grade strength.
