Socket Bit Set NEO tools hex 1/2" H4–H17 long, 9 pieces (08-706)

Long hex socket bit set by NEO tools for use with 1/2" drive ratchets and extensions. The set contains nine long hex bits in sizes H4 through H17, designed to reach recessed hex fasteners and provide extra engagement depth compared with standard-length bits. The bits are intended for mechanical work, assembly and maintenance where extended reach and a 1/2" drive interface are required.

Advantages

The long design of these hex bits enables access to deep-set screws and bolts without removing surrounding components. Compatibility with 1/2" drive tools offers stable torque transfer for demanding fastening and loosening operations. The set covers a wide size range from H4 to H17, reducing the need to switch tool types and improving workflow efficiency.

Suitable for

• Automotive repair and engine maintenance
• Industrial assembly and production lines
• Maintenance and service work on machinery with recessed fasteners
• Workshop and professional trades requiring 1/2" drive hex bits

Key specifications

• Drive type: 1/2" (square drive)
• Bit type: long hex (internal hex / Allen)
• Sizes included: H4, H5, H6, H7, H8, H9, H10, H12, H17
• Quantity: 9 pieces
• Intended application: fastening and loosening hex fasteners in recessed or hard-to-reach locations

How to use

Select the hex bit matching the fastener size and insert it into a compatible 1/2" drive ratchet or extension. Seat the bit fully into the hex socket of the fastener to ensure even torque distribution and reduce the risk of rounding. Apply steady torque while keeping the drive axis aligned with the fastener; use extensions to reach deep-set bolts or to work around obstructions. Inspect bits before use for wear or damage and replace if signs of rounding or cracking appear.

Usage recommendations

For optimum performance, use the set with a quality 1/2" drive ratchet or torque wrench and avoid excessive impact loads unless the bits are specifically rated for impact use. Store bits in a dry toolbox or case to prevent corrosion and check bit fit regularly to maintain safe and accurate fastening.
