Stahlwille Combination Wrench, 5/16 in x 5/16 in - ST 40572020

Versatile and durable, a combination wrench is essential for any toolbox. Featuring an open-end and a boxed-end, it allows for efficient fastening and loosening of various nuts and bolts. Crafted from high-quality materials, it ensures longevity and reliable performance in any setting.

Features:

• Made in Germany
• Special manufacturing process makes thin-walled rings possible - perfect for working in places that are difficult to access
• The AS-Drive profile prevents damage to the fastener caused by force being applied to the edges of the nut or bolt
• The double-T profile gives the wrench outstanding flexural strength
• The distinctive STAHLWILLE rounded finish ensures the wrench is comfortable to hold and is easy to grip, ensuring safe working, even with oily hands

Properties:

• Imperial, identical end sizes
• Jaw angled 15 deg
• Ring with bi-hex and AS-Drive profile
• Ring-end cranked 15 deg
• Durable, slim and lightweight design
• High flexural strength due to double-T profile
• STAHLWILLE's rounded finish ensures a non-slip, pleasant feel
• Drop-forged, hardened, and cooled in an oil bath
• HPQ high performance steel, chrome-plated
• Fed. Spec. GGG-W-636 E

Technologies and Features:

• High Performance Quality (HPQ)
  • Our HPQ tool is made of wear-resistant high-performance steel, yet is thin-walled and lightweight. It withstands high torques and is ideal for work in confined spaces such as turbines
• Anti-Slip-Drive
  • The special AS-Drive profile makes high force transmission to the flats of bolts and nuts possible without damaging them. This also prevents stripping of the bolt head
• Double-T profile
  • Our ring, open-ended and combination wrenches have an additional recess in the middle of the tool. Similar to the principle of a double-T beam, this provides a tremendous load capacity and maximum strength whilst reducing weight
• Thin-walled rings
  • The thin-walled diameter of our rings makes it easier to work in confined spaces. The ring wall is deeper than standard nuts, which prevents jamming
• Offset Shaft Design
  • Our wrenches are specially designed with additional reinforcement in the load zones where the greatest amount of force is transmitted - namely where the jaw meets the shank - in order to prevent deformation

Product Highlights:

• A solution for every situation
  • Our combination wrenches are available in different versions (metric, imperial, long, with Spline-Drive profile) and as sets in textile bags, roll-up tool bags or TCS inlays
