1/4 inch screwdriver bit hexagon socket 3 mm, 50 mm long, zinc phosphated, pack of 5 - Bahco 59S/50H3

A hexagon socket screw at the bottom of a bore or behind a cover is hard to reach with a 25 mm bit, and every add-on extension introduces play into the joint. This bit measures 50 mm and works straight out of the bit holder. Size 3 mm matches socket head cap screws of size M4 to DIN EN ISO 4762.

Benefits in use

• Tool length of 50 mm instead of the usual 25 mm, deep seated screws are reached without an adapter in between.
• 1/4 inch drive to DIN 3126-E 6.3 and ISO 1173, so the bit fits common bit holders, ratchet screwdrivers and cordless drivers.
• Size 3 mm for hexagon socket screws, typical for socket head cap screws M4 to DIN EN ISO 4762.
• High performance steel alloy as the tool material, laid out for repeated fastening work in trade and industry.
• Zinc phosphated surface as corrosion protection during storage and workshop use.
• Five bits per pack in a plastic box, which keeps the stock at the assembly bench predictable.
