  • 3/8 in Drive Slotted Screwdriver Bit Sockets Print The Slotted Bit Socket has DirectTorque™ technology to help prevent rounding of fasteners and to provide better grip.
  • Features and benefits. 3/8-inch drive slotted screwdriver bit sockets; 5/16-inch tip size; 3/64-inch tip width; 3-inch overall length.
  • Screwdriver Bits The Ultimate Guide. A screwdriver bit is a tool for driving screws and one that can be fitted to most drilling power tools. All screws have a head with a contour such that an appropriate screwdriver tip can be engaged in it in such a way that the application of sufficient torque to the screwdriver will cause the screw to rotate.

Torx® Bits

Torx® fasteners are becoming more and more common in automotive and appliance assembly. Apex provides a full selection of bits for Torx screws.

Torx Plus® Bits

Torx Plus® bits and fasteners feature a greater engagement area for higher torque transfer and reduced camout when driving Torx Plus® fasteners. They can provide up to 100% more drive cycles. Torx Plus® bits are not compatible with standard Torx® fasteners.

Pozidriv® Bits

The shallow 'cross' indention in the screw head identifies a Pozidriv® fastener. The Pozidriv® bit and recess design provides contact than a standard Phillips for more torque with less possibility of camout.

Sel-O-Fit® Bits

Sel-O-Fit® bits are designed to provide a more efficient means of driving Pozidriv® screws. The Sel-O-Fit® bit places torque on the strongest and most mechanically advantageous portion of the driver tip. This allows more torque to be applied while minimizing the possibility of breakage and camout. Sel-O-Fit® is a registered trademark of Cooper Industries.

Quadrex® Bits

The Phillips/square screw drive, also known as the Quadrex® or SPAX screw drive, is a combination of the Phillips and Robertson screw drives. While a standard Phillips or Robertson tool can be used, there is a dedicated tool for it that increases the surface area between the tool and the fastener so it can handle more torque.

Frearson Bits

The Frearson recess is designed so that any size bit will fit any size recess. Choose bits on the basis of body diameter - the larger the screw, the larger the body diameter.

B.N.A.E Bits

French recess bits. The name comes from the Bureau de Normalisation de l'Aéronautique et de l'Espace.

Socket Head with Square Drive

We carry Socket Head Bits with Square Drive Adapters in both SAE and Metric measurements. The socket head bit is one of the most common screw drives. It is used in automotive repair, technology and heavy industry sectors, and the aviation industry.

Tri Slot Screwdriver

Square Recess Bits

A square, also known as a Robertson, screw drive has a square-shaped socket in the screw head and a square protrusion on the tool. Both the tool and the socket have a taper, which makes inserting the tool easier, and also tends to help keep the screw on the tool tip without the user needing to hold it there.

Pipe Plug Inserts

For pipe plug inserts use SC and RP bit holders found here.

Torq-Set® Bits

Torq-Set® is a cruciform screw drive used in torque-sensitive applications. The Torq-Set® head is similar in appearance to a Phillips drive in that it has a cross with 4 arms. In Torq-Set® however, the arms of the cross are offset from each other, so they do not align to form intersecting slots across the top of the head.

Mor Torq® Bits

The Mor Torq® drive, developed by the Phillips Screw Company, is a format used in automotive and aerospace applications. It is designed to be a lightweight, low-profile and high-strength drive, with full contact over the entire recess wing reducing risk of stripping.

Tri-Wing® Bits

The Tri-Wing®, also known as triangular slotted, screw drive has three radial slots. It is usually used on electronics equipment. Tri-Wing®, as the name suggests, is a screw with three 'wings' and a small triangular hole in the center. A variation is a kind where the three 'wings' are joined in the center (with no triangular hole).

Screwdriver Bits For Drills

Hi-Torque® Bits

The Hi-Torque® recess was designed to provide very high installation and removal torques, very shallow recess for use on 120° and 130° flush fasteners in thin skins, and to reduce the need for end-load of the driver by the operator while installing and removing screws.

Triple Square Bits

Triple square, also known as XZN, is a type of screw drive with 12 equally spaced tips, each with a 90 degree angle. Its name derives from overlaying 3 equal squares to form such a pattern with 12 right-angled tips

Finder Sleeves

A finder sleeve makes it easy to engage slotted fasteners with the bit. It guides the bit so there is less 'searching' for the proper alignment between blade and slot.
