Screwdriver Bits
Apex has manufactured top-quality screwdriver bits for decades in response to the ever-changing demands of fastener applications. These demands vary by industry, but are particularly exacting in aviation.
Special alloys have been developed that offer attributes suited to the specific demands of the aerospace industry. Apex bits of equal hardness from different brands will yield different results. We understand that determining the material/brand of choice can be a confusing process.
MRO Tools' staff, with nearly 40 years of experience in aerospace fasteners and tooling, will be pleased to offer specfic recommendations, and to clarify any confusion or you can browse the categories below, including B.N.A.E., Frearson, Hi-Torque, Phillips, Pipe-Plug, Pozidirv, Quadrex, Sel-O-Fit, Slotted, Socket Head, Square Recess, Torq-Set, Torx Plus, Torx, Triple Square and Tri-Wing.
 French recess bits. The name comes from the Bureau de Normalisation de l'Aeronautique et de l'Espace.
|
 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.
|
 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.
|
 Apex offers a full selection of Phillips Head screwdriver bits, which are common to aircraft assembly and maintenance.
|
 Apex Pipe-Plug Screwdriver Bits. For pipe plug inserts use SC and RP bit holders
|
 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. Apex offers a variety of Pozidirv screwdriver bits.
|
 Apex Quadrex Screwdriver 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.
|
 Apex slotted screwdriver bits have a single slot in the fastener head and the tool used to drive a slot is called a slot-head, flat-tip, or flat head.
|
 Apex Socket Head (Hex-Allen) Bits with Female Square Drive Adapters
|
 The hex socket screw drive has a hexagonal recess.
|
 The four sides of Apex square recess screwdriver bits are at right-angles to each other. The opposite sides of square recess bits are parallel.
|
 Apex 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.
|
 The Torx Plus fastener and bit configuration gives a closer fit, 25% increased bit strength and up to 100% more drive cycles. This improved design gets even better when its made with Apex know-how.
|
 Torx fasteners are becoming more and more common in automotive and appliance assembly. Apex provides a full selection of bits for Torx screws.
|
 Triple square bits, also known as XZN bits, are 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.
|
 The tri-wing bit, also known as triangular slotted, screw drive has three radial slots. Tri-wing, as the name suggests, is a screw with three "wings" and a small triangular hole in the center.
