Overview
Scaled for 27 millimeter fasteners, the BILITOOLS B1R95731 weighs 1.15 kilograms according to its listing. That combination of size and weight points to a heavier tool meant for large nuts and bolts rather than fine work.
At roughly 2.5 pounds and 27mm capacity, this sits well above the small hand-tool class, closer to plumbing, automotive or industrial fasteners than delicate assembly. The category placement under Tools and Wrenches matches both title and specs.

Who it's for
Suited to tradespeople or DIYers dealing with large fasteners such as plumbing fittings or heavy machinery bolts. Overkill for small electronics or craft work.
Pros and cons
- Built for large 27mm fasteners
- Solid 1.15 kilogram build
- Fixed single capacity, no adjustability
- Weight makes it less suited to overhead work
Performance notes
The 27mm capacity fixes what fastener sizes the tool can turn, while the 1.15 kilogram weight suggests a solid build able to handle the torque larger fasteners require. No handle length or material is given, so grip comfort cannot be confirmed from the data.
