Westward 54TN03 10 mm 5-1/4" hex socket bit

Socket bit for 10 mm hex fasteners

The Westward 54TN03 is a 1/2-inch drive socket bit with a 10 mm hex tip and an overall length of 5-1/4 inches. It is made from alloy steel with a full polished chrome finish and meets ASME B18.3.2M-1979 standards. The extra-long socket depth and 3-1/2 inch insert length suit automotive and industrial maintenance tasks where deep recess access is required.

No bundled accessories or software

This product is a single hand tool supplied without any additional bits, adaptors, cases or lubricants. The absence of extras means the buyer receives only the socket bit itself, so any organisation, storage or complementary drive tools must be sourced separately. There is no software component associated with this mechanical fastener tool.

Limited to 1/2-inch drive and 10 mm hex

The bit fits only 1/2-inch square-drive ratchets or breaker bars and engages solely 10 mm hex fasteners with a six-point profile. It cannot be used with smaller or larger drive sizes, different tip geometries or imperial hex dimensions. The fixed overall length also restricts use in extremely confined spaces where a shorter bit would be necessary.
