## Long description

Wera 8790 HMA 13 mm 1/4" Hex socket bit is a compact hex bit designed for use with 1/4" drive bit holders and ratchets. It provides precise hex engagement for fastening and loosening hex-head fasteners in confined spaces and on assemblies that require a small-drive connection. The bit is made to deliver reliable torque transfer and repeatable fit for maintenance, assembly and automotive tasks where a 13 mm hex size combined with a 1/4" drive is needed.
Advantages
The Wera 8790 HMA offers accurate hex geometry to minimise cam-out and ensure even load distribution across fastener faces. Its compact 1/4" drive form factor allows use in tight spaces and with standard bit holders and ratchets. Built from durable materials and manufactured to precise tolerances, the bit provides consistent fit and dependable torque transfer over repeated use.
Suitable for
 Automotive maintenance and repair where a 13 mm hex fastener requires a small drive connection
 Mechanical assembly and disassembly tasks with limited access
 Workshop and service operations using 1/4" drive tools and bit holders
 Electrical and appliance servicing that requires compact, precise hex engagement
Key specifications
 Hex size: 13 mm
 Drive type: 1/4" (6.35 mm) square drive interface for bit holders and ratchets
 Bit profile: straight hexagon (internal hex / Allen) geometry
 Material and finish: hardened tool steel with protective surface treatment for wear resistance
 Length: compact length suitable for confined access (standard short bit form factor)
How to use
Insert the 1/4" drive end of the Wera 8790 HMA bit into a compatible 1/4" bit holder, adapter or ratchet until it engages securely. Place the hex end into the fastener recess, ensuring full seating to reduce the risk of rounding the fastener. Apply torque smoothly and maintain axial alignment while turning. For removal, reverse the direction and back the fastener out while keeping the bit engaged. After use, inspect the bit for wear and store it in a bit holder or toolbox to avoid damage.
Usage recommendations
Use the bit within the torque limits of your 1/4" drive tools and matching fastener specifications. Avoid excessive side loading and impact tools unless the bit and drive are rated for such use. Regularly inspect the hex tip for deformation and replace the bit when signs of rounding or significant wear appear to maintain secure fastener engagement.
