Proto Tools catalogue includes a wide range of sockets, wrenches, ratchets, screwdrivers, hex keys, pliers, snips, clamps, master sets, punches, chisels and tethered tools. Proto torque wrenches, also known as digital torque wrenches, provide a precise torque reading by measuring turning force electronically to avoid over tightening of fasteners. These wrenches are commonly used to apply consistent torque on assembled products for safety and quality control applications. They feature a digital display with visual alerts & an audible buzzer for delivering accurate torque output. Proto socket sets feature TorquePlus configuration with radius-corner design for shifting the stresses away from the corners and uniformly distributing over a large surface area. The internal design of these sockets further reduces rounding of the edges and offers more flexibility to turn worn out or rusted fasteners. Choose from a wide range of these quality wrenches & other company products, such as socket bits, hand-held punches & chisels on Raptor Supplies.
Proto Tools torque wrenches (manufacturer's part numbers) generally cross individual reference to the equivalent AMPCO Metal model numbers. So, if you are looking for a competitor torque wrench that is either out of stock or obsolete, chances are Raptor Supplies has the equivalent Proto torque wrenches available. Customers can also cross-reference most of these couplings using the last five digits of the model numbers.
These Proto torque wrenches and steel crowfoot wrenches are small in size and require compact packaging. Hence, they are delivered in packs consisting of several pieces and are suitable for courier shipment and not air freight.

Proto Facom insulated ratchets are ideal for fastening nuts and bolts for applications prone to electrical leakage. These Proto professional tools have two colour warning handle insulation that changes colour to yellow if the insulation integrity is compromised during the operation. They have a spring ball tip for securing the sockets & accessories while fastening.
Proto offers various tools, including storage units, hand sockets, drive tools, impact sockets, wrenches, pliers, clamps, snips, screwdrivers, hex keys and torque wrenches.
Socket wrenches are designed to fasten nuts & bolts. However, these tools are not ideal for tight spaces as they need to be lifted after each fastening cycle. Whereas, ratcheting wrenches have pawls that enable the wrench to spin in one direction while turning the bolt in another.
No, regular sockets should not be used with impact wrenches. These sockets are likely to shatter against the power of impact wrench because of their thin wall design and construction material.
