** Where zero capacity is desired, the clamp with long screws should be ordered. These are indicated with an "L" in the product code. Features: • Especially designed for heavy duty service, frames are drop-forged and heat-treated for maximum strength and reduced springing. • Screws are made of special grade steel and are heat-treated for added strength not found in typical case-hardened screws. • To tighten, the square headed screw must be turned with a wrench. • Ideal for the most demanding applications such as construction and heavy industry. • Square head screw allows tightening with wrench for extra heavy duty clamping requirements. • Greater anvil surface for gripping larger work pieces and for greater stability.
