[52][fifty seven] The spline socket can also be desired above the hexagon socket in screws that have to be subjected to superior driving torque As well as in applications requiring high reliability with the fastener.[54][58] in comparison with the hexagon socket travel, spline socket drives are not as likely to strip for the same amount of torque; nonetheless, the spline socket push is not really far more strip-resistant than a Torx drive.[citation essential]
This lets you exert extra torque (and therefore the brand title 'Torx') having a reduce chance of injury to the head. these are typically wonderful, provided that you Have a very bit around. in any other case, you'll be ordering 1 or operating off to the store.
