SHD14309 Dimensions and Specifications
Buyers searching for TEKTON SHD14309 dimensions, overall length, weight, outer diameter, and well depth get a semi-deep profile that sits between shallow and deep sockets for restricted-reach access on the 3/8 inch drive platform.
Materials and Finish
- Chrome-vanadium steel construction with a mirror-polished chrome exterior
- Interior chrome plating supplemented with clear coat or paint for full corrosion coverage
Drive and Opening
- 3/8 inch square drive with detent grooves and beveled edges for secure ratchet engagement
- 12-point opening for more access positions on hex, double-hex, and square fasteners
Why Semi-Deep Beats Standard and Deep Sockets
Compared to a standard shallow socket, the SHD14309 semi-deep well reaches fasteners on longer studs; compared to a deep socket, it stays shorter and more rigid in tight bays. The 12-point design with radiused corners applies force to fastener flats, preventing round-off.

At $5.50, this 9 mm semi-deep socket undercuts typical big-box pricing for a comparable Tekton socket. Stack the SAVE15 coupon, and orders over $45.00 ship free (standard shipping otherwise $8.00). Bundle multiple sizes to hit the free-shipping threshold and maximize your discount.
Best Use Cases

- General assembly where fastener depth varies
How to Choose and Compare
Match socket size to fastener size (9 mm here), confirm 3/8 inch drive compatibility with your ratchet, and pick semi-deep when clearance is between shallow and deep requirements. Alternatives in the Tekton SHD143 series cover the full metric range, so build out your set size by size.
