Proxxon hex socket bit 1/2" H12 x 100 mm long (PR23483)

Proxxon hex socket bit 1/2" H12 x 100 mm long is a long-reach hex bit designed for use with 1/2" drive ratchets and torque tools. The H12 size head fits hex fasteners and the 100 mm length provides extra reach for recessed or hard-to-access bolts. Manufactured by Proxxon, this accessory is intended to deliver accurate engagement with hex heads while enabling work in tighter assemblies and deeper mounting positions.

Advantages

The extended 100 mm length allows access to recessed hex fasteners without removing surrounding components. A precisely machined H12 hex profile ensures a secure fit and reduces the risk of rounding the fastener. Compatibility with 1/2" drive tools offers versatility across hand ratchets, breaker bars and compatible impact adapters. The solid construction provides torsional stability during torque application.

Suitable for

• Automotive repair and maintenance where fasteners are recessed
• Mechanical assembly and disassembly in tight or deep spaces
• Maintenance tasks on machinery with recessed hex bolts
• Use with 1/2" drive torque tools for controlled tightening

Key specifications

• Drive type: 1/2" drive
• Hex size: H12 (12 mm across flats)
• Overall length: 100 mm
• Tool compatibility: hand ratchets, torque wrenches, impact adapters (1/2" drive)
• Material: hardened steel construction for torsional strength

How to use

Select the Proxxon H12 hex bit and attach it securely to a compatible 1/2" drive ratchet, torque wrench or impact adapter. Engage the hex bit fully with the fastener to ensure correct seating before applying torque. For torque-controlled applications, set the required torque on the torque tool and apply force evenly. When working in confined or recessed areas, maintain alignment between bit and fastener to avoid cam-out or rounding.

Usage recommendations

Use the bit with appropriate torque settings and hand or impact tools rated for 1/2" drive. Inspect the hex profile and bit shank for wear before use and replace if signs of rounding or damage appear. When accessing deeply recessed fasteners, ensure work area is stable and use extension adapters only if they maintain secure engagement.
