TOOLS & INSTRUMENTS

Hand tools are defined by their ergonomics, material composition, and mechanical precision. In industrial environments, these tools must meet specific technical standards (such as ANSI or DIN) to ensure safety and durability under heavy loads.

Key Technical Specifications

When evaluating industrial-grade hand tools, several technical factors determine their performance:

1. Material Composition and Hardness



Chrome Vanadium (Cr-V) Steel: The industry standard for wrenches and pliers. It offers high strength and resistance to abrasion.


S2 Tool Steel: Often used for screwdriver bits and hex keys; it is harder and more resistant to "cam-out" or stripping than Cr-V.


Rockwell Hardness (HRC): Most high-quality cutting tools (like wire cutters) have a hardness rating between 55–62 HRC.

2. Torque and Load Capacity



Proof Torque: The maximum torque a tool can withstand without permanent deformation. For example, a heavy-duty pipe wrench is rated based on the foot-pounds of torque it can handle relative to its handle length.


Precision Tolerances: For wrenches, the opening size must have a tight tolerance (often within hundredths of a millimeter) to prevent rounding off the edges of fasteners.
