Metal Wrench Set faster tools 02-2-0312, 4 pcs, hardness 62 HRC

Set of four metal wrenches by faster tools, model 02-2-0312, manufactured from hardened steel with a rated hardness of 62 HRC. The set contains four commonly used sizes designed for tightening and loosening fasteners in workshop, industrial maintenance and home repair tasks. The hardened construction improves wear resistance and extends service life under frequent use.

Advantages

The wrenches combine high material hardness with accurate jaw fit to reduce rounding of fastener heads. Hardened steel construction and heat treatment to 62 HRC deliver improved abrasion resistance and dimensional stability. The compact set includes multiple sizes to cover a range of common fasteners, reducing the need to switch tools during routine maintenance. The tools are designed for repeated use in professional and DIY environments.

Suitable for

• Tightening and loosening bolts and nuts in workshop repairs
• Routine maintenance of machinery and equipment
• Automotive and bicycle repair where hardened tools are preferred
• Home repair tasks requiring durable hand tools

Key specifications

• Set composition: 4 wrenches (four sizes as specified by the manufacturer)
• Material: hardened steel
• Rated hardness: 62 HRC
• Finish: industrial raw or protective coating depending on production batch
• Intended use: manual hand tool for fastening operations

How to use

Select the wrench size that matches the fastener head and place the jaw squarely onto the nut or bolt. Apply steady force with controlled wrist movement to avoid slipping; for higher torque use the longer wrench in the set. Inspect the contact fit and reposition if rounding or slippage occurs. After use, clean off debris and store the wrenches in a dry place to prevent corrosion and preserve the hardness-treated surfaces.

Usage recommendations

For safe and effective operation, use the correct size from the set to minimize wear on fasteners. Do not use the wrenches as hammers or pry bars. Regularly inspect the jaws for wear and maintain clean contact surfaces. If higher torque is needed, use an appropriate torque wrench or apply controlled leverage while observing manufacturer torque limits for fasteners.
