Is this the right one for you?

Check these four things before you order:

• Your screws have inch hexagon sockets; the key size must match the socket exactly - a loose key rounds the socket.
• The sizes you need are within hexagon sizes 1/16" to 3/8".
• Standard length suits you: compact, strong, and the usual choice for toolkits and maintenance.
• You want speed and grip on repetitive work - the T handle spins fast and gives a full-hand hold for the final torque.

Why choose TVS Sundram Fasteners

• Made by Sundram Fasteners Limited, a TVS group company making high tensile fasteners since 1966: first Indian company with ISO 9000, IATF 16949:2016 certified, Deming Prize 2018 for 17 plants.
• Every lot is backed by a BIS, NABL and ISO/IEC 17025 certified laboratory - tensile, fatigue, torque-tension, salt spray and coating thickness testing - as described in SFL's technical product catalogue (September 2026 edition).
• Made to SFL's own standard, with every dimension published in SFL's technical catalogue.
• Hardened and accurately sized hexagon, so the key fills the socket and does not round it.

How to choose and fit

1. Choose the key by the socket size of the screw, not by the screw diameter; the screw tables on this site list the key size for each diameter.
2. Push the blade fully into the socket before turning - a partly inserted key rounds the socket.
3. Spin the handle with the fingers to run the screw down, then take the full-hand grip on the T for the final torque; do not extend the handle.

Where it is used

• assembly lines with many socket screws
• maintenance and service work
• workshops and tool rooms
