It delivers 4,880 pounds of clamping pressure through a 0.85-inch diameter high carbon steel spindle, making it well suited for heavy-duty fabrication, woodworking, and metalworking tasks. The T-handle design gives the operator firm, controlled grip when applying load. The electrogalvanized finish provides corrosion resistance for shop and job-site environments. Weighing 12 pounds, this is a substantial, production-grade tool intended for professional tradespeople and skilled fabricators who need repeatable, high-force clamping.\u003c\/p\u003e\u003cp\u003eThe STB-12 is used in professional woodworking shops, metal fabrication facilities, and general construction assembly where a wide throat clearance and high clamping force are required. The 7-inch throat depth accommodates thicker workpieces and deeper reach applications. The standard rail profile with a swivel pad allows the clamp to self-adjust to irregular or angled surfaces, reducing workpiece marring during assembly operations. This clamp is a common tool in cabinet shops, structural steel fabrication, and HVAC ductwork assembly jigs where repeatable square clamping is critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eF-style sliding arm design with 12-inch maximum clamping capacity\u003c\/li\u003e\n\u003cli\u003e7-inch throat depth for deep-reach clamping on thick or wide workpieces\u003c\/li\u003e\n\u003cli\u003e4,880 pounds of clamping pressure for heavy-duty production use\u003c\/li\u003e\n\u003cli\u003eForged steel T-handle for controlled, high-torque tightening\u003c\/li\u003e\n\u003cli\u003eHigh carbon steel spindle at 0.85 inches in diameter for strength and durability\u003c\/li\u003e\n\u003cli\u003eElectrogalvanized finish resists corrosion in shop and job-site conditions\u003c\/li\u003e\n\u003cli\u003eIncludes standard rail profile and swivel pad for surface conformance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard F-style bar clamp for use with flat, parallel, or slightly angled workpieces in woodworking, metalworking, and fabrication applications.

Avoid overtightening on finished surfaces even with the swivel pad in place, as the heavy-duty steel pads can leave impressions under high pressure. Inspect the spindle threads and sliding arm mechanism periodically for debris or damage that could reduce clamping accuracy. Standard shop-safety practices apply when working with high-force clamping tools.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eClamp Type\u003c\/strong\u003e: F-Style\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Capacity\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThroat Depth\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClamping Pressure\u003c\/strong\u003e: 4,880 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpindle Diameter\u003c\/strong\u003e: 0.85 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpindle Material\u003c\/strong\u003e: High Carbon Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRail Size\u003c\/strong\u003e: 1-37\/64 x 25\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRail Length\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandle Style\u003c\/strong\u003e: T-Handle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandle Material\u003c\/strong\u003e: Forged Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePad Type\u003c\/strong\u003e: Heavy-Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePad Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Electrogalvanized\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Standard Rail Profile and Swivel Pad\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: STB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 12 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: BESSEY\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: STB-12\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BESSEY","offers":[{"title":"Default Title","offer_id":51538287558962,"sku":"STB-12","price":244.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9181530bca34d47e1b50213b078db6a6.jpg?v=1785821898","url":"https:\/\/voomisupply.com\/products\/bessey-stb-12-sliding-arm-bar-clamp-12-in-f-style","provider":"Voomi Supply","version":"1.0","type":"link"}
