Understanding Mechanical Properties of Hand Tools

When selecting a hand tool, it's crucial to ensure its reliability and durability. This involves assessing two key mechanical properties:

1. Stiffness

Stiffness refers to a metal material's ability to withstand elastic deformation when subjected to force. It indicates how much a material can resist bending or stretching without permanent deformation.

2. Strength

Strength denotes a metal material's capacity to withstand plastic deformation and avoid fracture under external forces. It measures the material's resistance to breaking or yielding under stress.

Several measurements are used to evaluate these properties:

• Toughness is often indicated by elongation A (%)
• Strength is assessed through yield strength Rp0.2 (MPa) and tensile strength Rm (MPa)
• Stiffness is determined by the elastic modulus E (MPa)
• Hardness is measured using Rockwell hardness HRB

Our products adhere to DIN and ANSI standards and are engineered for superior performance. You can have full confidence in the quality and reliability of our tools.
