Blue Spot Tools 75mm (3") Deep Throat G-Clamp

MPN: 10051

Barcode: 5028734100518

Size: 75mm (3")

Weight: 0.64kg

Overview:

The Blue Spot Tools deep throat G-clamp has a malleable cast iron frame with a fine thread and reinforced shoulders. The deep throat design gives you greater reach into workpieces than a standard clamp of the same jaw capacity.

It features a steel swivel screw that drives the clamp. The ball and socket head maintains contact on angled or uneven surfaces. Use the Tommy bar to tighten the jaw firmly in position. The clamp carries the Blue Spot Tools Lifetime Guarantee.

Key Features and Benefits

• Malleable Cast Iron Frame: Resists cracking under impact and repeated load better than standard cast iron.
• Reinforced Thread Shoulders: Adds material at the highest-stress section of the thread, lowering the risk of thread failure under heavy load.
• Ball and Socket Head: Seats flat against angled and uneven surfaces, spreading pressure more evenly regardless of surface angle.
• Tommy Bar Handle: Provides mechanical leverage, making it straightforward to tighten the jaw by hand without a separate tool.
• Steel Swivel Screw: Transfers clamping force consistently to the work surface throughout the full tightening stroke.
• Extended Throat Depth: Reaches further from the material edge than a standard G-clamp, giving access to panel interiors and deeper joint positions.

Typical Applications

• Holding timber joints during glue-ups until the adhesive sets
• Securing workpieces to a bench while cutting, drilling, or sanding
• Clamping boards or panels at points further from the edge than a standard G-clamp can reach
• Light fabrication, metalworking bench setups, and welding preparation
• Furniture making and joinery assembly
• Holding components in position while the adhesive or bonding agent sets

How to Use

• Protect the Surface: Place a piece of scrap wood between the jaw pad and the workpiece to prevent marking.

• Open the Jaws: Turn the Tommy bar anti-clockwise to open the jaw wide enough to fit over the workpiece and work surface.

• Position the Clamp: Slide the open jaw over the workpiece at the point where you want pressure applied.

• Tighten the Screw: Turn the Tommy bar clockwise to advance the screw until it makes contact with the work surface.

• Check Head Seating: Confirm the ball and socket head sit flush before applying full clamping pressure. Do not over-tighten.

Frequently Asked Questions (FAQs)

• What is the difference between a deep throat G-clamp and a standard G-clamp?
  A deep throat G-clamp has a longer frame, placing the screw further from the frame's inner edge. This lets you clamp further into a panel or board than a standard G-clamp of the same jaw capacity.

• What are G-clamps used for?
  G-clamps hold workpieces together or to a work surface during gluing, cutting, drilling, and welding. They apply consistent pressure at a fixed point, keeping materials stable while you work.

• Is a G-clamp the same as a C-clamp?
  Yes - the terms refer to the same type of tool. G-clamp is the common British name; North Americans more commonly say C-clamp. The frame shape resembles both letters, depending on the viewing angle.

• Why is malleable cast iron used for G-clamp frames?
  Malleable cast iron undergoes heat treatment to reduce the brittleness of standard cast iron. This makes it better able to resist cracking under impact and repeated load. These properties suit the demands of a clamp frame in regular use.

• Can G-clamps be used for welding?
  Welders commonly use G-clamps to hold components in position before and during work. For welding tasks, position the clamp clear of the weld zone. Inspect it afterwards for heat or spatter damage.

Summary

This 75mm (3") G-clamp from Blue Spot Tools features a deep throat design, reaching further into workpieces than a standard clamp allows. The malleable cast iron frame and ball and socket head apply firm, even pressure across flat and angled surfaces. It carries the Blue Spot Tools Lifetime Guarantee.
