Screwdriver bit TORX T5, 25 mm, 1/4 inch hex C 6.3, pack of 5 - Bahco 59S/T5

Hexalobular screws need a bit that fills all six lobes. The Bahco 59S/T5 carries the T5 profile on a 25 mm long 1/4 inch hex shank of form C 6.3 and transfers torque through the flanks rather than the corners.

Benefits

• The TORX T5 profile engages across six rounded flanks, spreading the load over a larger area than a cross recess and holding the bit in the screw without end pressure.
• Shank form C 6.3 with a 6.3 mm hex to DIN 3126 and ISO 1173, so the bit fits bit holders, bit ratchets and machine chucks without an adapter.
• Tool length 25 mm, the compact standard length for hand drivers and short bit holders.
• Zinc-phosphated surface on a high performance steel alloy, which protects against corrosion in the workshop and inside the bit box.
• Sold as a pack of 5 identical bits in a plastic box, so the size in use is restocked at the workplace instead of being ordered one by one.

Technical data

Applications

• precision engineering and electronic enclosures
• control units, sensors and small drives
• test and measuring equipment in service work
• repair of assemblies with small hexalobular screws

Compatibility and scope of delivery

The 6.3 mm hex shank of form C 6.3 is standardised, so the bit works with 1/4 inch bit holders, bit ratchet screwdrivers and bit adapters from any manufacturer. The scope of delivery is 5 bits of profile T5 in a plastic box. A bit holder or screwdriver handle is not included and is ordered separately.

Standards and conformity

The bit shank follows DIN 3126-C 6.3 and ISO 1173. The hexalobular recess of the matching screws is described in ISO 10664. The manufacturer property table lists the bit as not VDE tested, so it is not intended for live working to IEC 60900. No statement on ESD capability to IEC 61340-5-1 is available for this item.
