These hex socket bits come with a hex bit on one end that fits inside the hexagonal-shaped indentation in the fastener head.

Slotted hi-torque socket bits have a slotted bit on one end that fits inside slotted (single horizontal groove) fastener heads. They can apply more torque to fasteners with a slotted head than a standard slotted socket bit.

These ball hex socket bits come with a ball hex bit on one end that fits inside the hexagonal-shaped indentation in the fastener head and allows use at an angle to tighten and loosen fasteners in tight spaces.

Torx socket bits have a Torx bit on one end that fits inside the Torx indentation in the fastener head.

Phillips socket bits come with a Phillips bit on one end that fits inside the Phillips-style indentation in the fastener head.

These 12-point socket bits fit the 12-point indentation in the fastener head.

Slotted drag link socket bits come with a slotted bit on one end that fits into the slotted (single horizontal groove) fastener head. Fasteners are for use on a vehicle’s drag link steering linkage.

These slotted socket bits have a slotted bit on one end that fits inside the slotted (single horizontal groove) in the fastener head.

Tamper-resistant Torx socket bits have one end that fits a tamper-resistant Torx indentation in the fastener head. The tamper-resistant Torx fasteners are for use in locations where theft or vandalism are a concern.

These Torx Plus socket bits have one end that fits a Torx Plus indentation in the fastener head. These bits are less likely to cam out, where the Torx bit slips out of the indentation on the fastener head once the torque required to turn the fastener exceeds a certain amount. They allow Torx Plus fasteners to be tightened to a higher torque compared to standard Torx fasteners.

Tamper-resistant hex socket bits have one end that fits a tamper-resistant, hexagonal-shaped indentation in the fastener head. The tamper-resistant hex fasteners are for use in locations where theft or vandalism are a concern.

Hex insulated socket bits have an insulated handle and shaft to protect from electric shock and reduce the possibility of electrical arcing caused by a short circuit from a noninsulated tool. Bits should be used with insulated drive tools for protection from electric shock. One end of the bit fits inside the hexagonal-shaped indentation in the fastener head.

Hex torsion socket bits have a torsion construction that allows the bit to flex and avoid damage to the bit and the hexagonal-shaped indentation in the fastener head.

Pozidriv socket bits have a Pozidriv bit on one end that fits inside the Pozidriv indentation in the fastener head.

Square socket bits have a square bit on one end that fits inside the square indentation in the fastener head.

Tri-wing socket bits fit the tri-wing indentation in the fastener head. Tri-wing fasteners are often used on electronic equipment.
