Built as part of Bessey's global classiX platform, this clamp delivers uniform holding pressure and rigid performance for shop assembly and maintenance work.\u003c\/p\u003e\n\u003cp\u003eFeaturing a drawn, heat-treated, tempered, and quenched steel rail and fixed top jaw, the frame resists flexing under load while maintaining consistent alignment. The hardened spindle with ACME threads provides smooth mechanical advantage and rapid travel, while the attached standard swivel pad articulates to keep flat contact on varying workpiece surfaces. A sliding T-bar handle allows the operator to apply up to 550 lbs. of clamping force efficiently in compact setups.\u003c\/p\u003e\n\u003ch3\u003eFeatures \u0026amp; Benefits\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eclassiX Series Platform:\u003c\/strong\u003e International high-value all-steel clamp design manufactured to Bessey quality standards.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeat-Treated Steel Profile:\u003c\/strong\u003e Drawn rail and fixed top jaw are heat-treated, tempered, and quenched for strength and deflection resistance.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eACME Threaded Spindle:\u003c\/strong\u003e Smooth-running hardened spindle delivers reliable clamping force with minimal effort per turn.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard Swivel Pressure Pad:\u003c\/strong\u003e Crimped-on swivel pad articulates to maintain full contact across workpiece faces.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSliding T-Bar Handle:\u003c\/strong\u003e Heavy-duty Tommy bar handle allows efficient high-torque tightening in tight working spaces.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e(1) Bessey GS12-8K 4 in. classiX All-Steel Bar Clamp\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eSelect the GS12-8K for compact 4 in. clamping capacity with a 3-1\/8 in. throat depth.
