Description
The Crowring spanner No. 440a applies the drive with a lateral offset and so reaches bolts and nuts in size 2 inch that a standard socket cannot access. It is driven via the 1/2 inch square drive, with a length of 83.2 mm and a weight of 277 g.
Benefits
- Bi-hex with AS-Drive profile: power is transmitted via the flanks, protecting the corners of the fastener
- Closed ring fully surrounds the bolt head and does not slip off
- 1/2 inch square drive for ratchet, extension or torque wrench
- Chrome Alloy Steel, chrome-plated, for corrosion protection and a long service life
Applications
For bolted joints with inch sizes in hard-to-reach places, for example in mechanical and engine engineering and in maintenance. Combined with a torque wrench, it allows controlled tightening of joints where there is no room for a socket.
