Socket Bit Wera 05004538001 16 mm 3/8"

The Wera 05004538001 16 mm 3/8" socket bit is a precision tool engineered for compatibility with 3/8" drive systems. It is manufactured from hardened steel and finished to resist wear, providing consistent performance for fastening and loosening bolts and nuts with a 16 mm head. The design emphasizes secure engagement with fasteners and straightforward insertion into compatible ratchets, extensions, and bit holders.

Advantages

The socket bit combines a compact 16 mm profile with a 3/8" drive interface, offering reliable torque transfer and accurate fit on hexagonal fastener heads. Durable material and a hardened surface reduce rounding and wear under frequent use. Its precise machining ensures smooth seating on the fastener and simplified removal after tightening or loosening operations.

Suitable for

• Assembling and disassembling mechanical components with 16 mm hex fasteners
• Maintenance work in automotive and machinery applications requiring a 3/8" drive
• General workshop and DIY tasks where a reliable 16 mm socket bit is needed

Key specifications

• Drive type: 3/8"
• Socket size: 16 mm
• Material: hardened steel (wear-resistant finish)
• Profile: hexagonal (six-point) for standard bolts and nuts
• Compatibility: standard 3/8" ratchets, extensions and bit holders

How to use

Select a compatible 3/8" ratchet or extension and firmly attach the 16 mm socket bit to the drive square until it locks in place. Position the socket squarely onto the fastener head and apply steady torque, maintaining alignment to avoid rounded edges. For removal, reverse the ratchet direction and keep steady pressure while backing out the fastener. After use, wipe the bit clean and store it in a tool box or socket tray to prevent corrosion and loss.

Usage recommendations

Use with hand ratchets or torque tools rated for the intended torque range; avoid excessive impact with incompatible power tools unless the bit and tool are specified for impact use. Inspect the bit regularly for wear and replace if the profile shows rounding to maintain safety and effective torque transfer.
