Set includes sizes: 5/16" thru 5/8". Bondhus ProHold® socket bits are designed to be strong, and to save time and money.  The unique holding buttons "snap" the bit securely into any six point socket, allowing the tool user to buy just the bit, rather than an expensive socket and bit assembly.  All Bondhus ProHold socket bits are manufactured from Bondhus' exclusive Protanium Steel, which is up to 20% stronger than competitor tools and finished with its' proprietary ProGuard corrosion resistant finish.  ProHold socket bits are protected by US and foreign patents, ensuring ProHold socket bits are only available from Bondhus.
