Frequently Asked Questions

What is the advantage of a 40° bent wrench?

The 40° bent head allows the wrench to reach fasteners in tight or awkward spaces where a straight wrench cannot be used, such as in engine rooms or pipe fittings. It also provides better leverage and reduces hand strain.

Is this wrench suitable for marine environments?

Yes, it is made from hardened alloy steel, which offers good corrosion resistance and durability for marine applications. However, proper maintenance like cleaning and oiling after use is recommended to extend its life.

What is the difference between 12-point and 6-point wrenches?

A 12-point wrench can engage a fastener every 30 degrees of rotation, making it easier to use in tight spaces. It is suitable for hex bolts and nuts, but may not be as strong on highly torqued fasteners as a 6-point version.

What is the overall length of this wrench?

The overall length is 345 mm, providing good leverage for loosening or tightening large bolts.
