A Combination Spanner Is A Versatile Hand Tool Used For Tightening Or Loosening Nuts And Bolts. It Has Two Different Ends: One Open-ended And The Other With A Ring Or Box-end, Both Designed To Fit The Same Size Of Fastener. This Dual-functionality Makes It A Convenient Tool For A Wide Range Of Mechanical, Automotive, And Household Applications.
- Angled Open-end:the Open End Of The Spanner Is Often Slightly Angled (Around 15 Degrees) From The Handle. This Allows The Tool To Be Flipped Between Turns, Providing More Flexibility In Tight Spaces And Enabling Better Access To Fasteners In Awkward Positions.
- Offset Ring-end: the Ring-end Of The Combination Spanner Is Usually Offset By About 15 Degrees As Well. This Helps To Avoid Knuckle Injuries By Providing Better Clearance Between The Hand And The Surface Being Worked On, Especially When Working On Flat Surfaces Or Recessed Bolts.
