SW13a - Stahlwille Combination Spanner 

• DIN 3113 Form A
• ISO 7738 Form A
• Chrome Alloy Steel, chrome plated.

  Descriptions

• Made from drop forged high-grade special Chrome Alloy Steel
• Has been optimally hardened in continuous furnaces with no scale build-up or skin decarburization.
• Has been gently quenched in oil.
• It is extremely strong yet light-weight due to Stahlwille's 'double-T profile'.
• Stahlwille's unique plating method prevents the problem of chrome flaking.
• More material is added where the greatest loads in the spanner are to be found.
• Sturdy, slim and light tools which also facilitate working in confined spaces due to their compact designs.
• Snug-fitting, skin-friendly surfaces

Key benefits when tightening and loosening screws

• Tougher than any bolt due to the forged double hex.
• Thinner than conventional rings, thus facilitating work in confined spaces.
• Higher than standard nuts. This prevents the spanner jamming on the nut.
