PROTO

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.

Things To Consider

Cross-Reference Alternatives

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.

Shipping

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.

Frequently Asked Questions

Which tools are offered by Proto?

Proto offers various tools, including storage units, hand sockets, drive tools, impact sockets, wrenches, pliers, clamps, snips, screwdrivers, hex keys and torque wrenches.

What is the difference between a socket wrench and a ratchet?

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.

Can the standard / regular sockets be used with impact wrenches?

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.
