Spline-Drive Adaptor 447aSP 3/8" Internal Square Drive 3/8" for Hand Use - Stahlwille 02480024

Screws with an external Spline-Drive profile cannot be tightened reliably with hex or bi-hex sockets. The Stahlwille 447aSP adaptor engages the 3/8 inch spline profile with a positive fit and transmits the torque through a 3/8 inch internal square drive. With a profile height of 8 mm and a head diameter of 14.9 mm, it also reaches fasteners in tight spaces.

Benefits

• Precise fit on external Spline-Drive screws, the load is spread across the flanks of the profile
• Designed for fasteners to the MS-33787 and MIL-W-8982 specifications
• HPQ high-performance steel (High Performance Quality) for high load capacity in a compact size
• Gunmetal finish, matt and low-reflection
• 3/8 inch internal square drive for ratchets, extensions and torque wrenches with a 3/8 inch output

Applications

Assembly and maintenance of components with Spline-Drive screws as specified in MS-33787 and MIL-W-8982. Combined with a torque wrench for controlled tightening by hand.
