Stahlwille Inch combination spanners, 1" AF

Stahlwille 13a is the inch-size version of the 13: a combination spanner range in 33 sizes from 3/16" to 2" across flats, from 95mm to 530mm long. Each spanner has the same size at both ends: an open end with the jaw angled at 15° and a 12-point ring offset by 15°.

The ring has the Stahlwille Anti-Slip-Drive (AS-Drive) profile, which puts the force on the flanks of the bolt or nut rather than the corners. The spanners are Chrome Alloy Steel, chrome-plated. The spanners are drop-forged, hardened and cooled in an oil bath, with a double-T profile for bending strength, a round finish for grip, thin-walled rings for hard-to-reach fastening points and a reinforced transition from jaw to shaft, where the highest forces act (Offset Shaft Design).

Key specifications

Choosing the right option

Pick the size by the inch width across flats of the fastener; both ends are the same size, and the range includes the less common 13/64", 15/64", 19/32" and 25/32". For metric sizes see the Stahlwille 13 combination spanners. Inch ring heads with a double open end are in the 10a MOTOR imperial double open end spanners, and the SW13A/10 imperial combination spanner set (10-piece) and SW13A/20 imperial combination spanner set (20-piece) give a spread of inch sizes in one pack.
