Socket cap screws are a headed and externally threaded part designed for insertion through a close tolerance, internally tapped hole and mated with a nut. Tension on the socket cap screw is induced by rotation of the screw head. There is a hex socket in the head that accepts a hex wrench to tighten the socket cap screw. The point at the threaded end of the socket cap screw is machined flat so it will fit into a drilled hole.
Button head socket cap screws have a domed-shaped head that is wider and has a lower profile than a socket head cap screw. -
Metric Dowel Pins
(242)
Dowel pins have ground cylindrical sides with both ends chamfered. Dowel pins are used where precise locating of mating parts is necessary, but with relatively minor wear or shock factors.
Dowel pins are often used as a plug gage, hinge, or shaft. Their precise tolerance makes them excellent for achieving proper alignment of parts in high-speed assemblies. -

Flat head socket cap screws are similar in design to a button head socket cap screw but with an 82º countersunk flat head. -
Flat washers are used under bolt heads or nuts to increase the bearing area or offer greater hardness, so that the nut or bolt can be rotated without distortion of the bearing surface. Flat washers are also used to give tightness to a joint, to prevent leakage, and especially to distribute pressure under the head of a nut or bolt. -

Hex bolts are bolts with a hexagonal head on one end, with no washer face on the bearing surface and a threaded shaft on the other end. Hex bolts are tightened with a wrench and are used to connect metal parts. (The body tolerances of hex bolts are not as close as those of hex cap screws.) -

Hex flange nuts are hex nuts with a bottom circular flange that is larger than their top hex section. Being all-metal, they do not have the temperature and chemical limitations of non-metallic (such as nylon) insert type lock nuts.
The protruding circular flange increases the nut's bearing surface allowing them to be used with irregular and oversized holes. Commercial and industrial applications include lawn and garden equipment and truck manufacturing. -
A hex key is a six-sided shaped bar bent at a 90º angle at one end. A hex bit is an unbent piece of such a bar.
They are designed to be inserted into a like-sized, hollow recess of a socket cap screw to manually tighten or loosen the fastener. -
Hex nuts are six-sided, internally threaded fasteners, mated with bolts, studs, screws, and other externally threaded products. The addition of the hex nut ensures that the bolt, etc., stays in place. -

Low head socket cap screws are similar in design to a socket head cap screw except the head height is 50% shorter and the socket size is smaller. -
Nylon insert lock nuts are self-locking nuts, six-sided nuts with nylon-filled collars at their back end. These collars adhere to the thread of the fastener bolt or screw they are being used with. When a bolt or screw reaches the collar, the threads and nylon form a tight, frictional fit, restricting movement of the fastener.
Nylon-insert locknuts are excellent for use where a long-term lock is necessary, or to prevent loosening due to vibration. -

Metric Socket Set Screws
(643)
Socket set screws are headless and are threaded over their entire length. There is a hex or square-shaped socket at the top of the drive in place of a head. Socket set screws come with either cup or knurl cup points shaped to bear on a mating part. The fact that the socket set screw is without head allows it to go in flush.
Socket set screws are often found in electronics, in pulleys and shafts, and other places where flush mounting and space are important concerns. They are also used for internal wrenching and where frequent disassembly or adjustment occurs. -
Socket shoulder screws (also called stripper bolts) are ground to very close tolerances, with a thick shoulder usually running 80 percent of the length of the shaft. In measuring the socket shoulder screw, it is the diameter and length of its shoulder that determines its size. The socket shoulder screw does not have a point. The socket head is a recessed head in which the sides of the recess are parallel to the body axis, into which a wrench fits.
Socket shoulder screws are used in applications requiring low limited clearance, where parts may not be thick enough to be counterbored, and/or where loading capacity is not critical. -
Lockwashers are used under bolt heads or nuts to increase the bearing area or offer greater hardness, so that the nut or bolt can be rotated without distortion of the bearing surface.
The surface of a split lock washer is bent or crimped so that the shape will prevent loosening under stress. Split lock washers feature a gap cut into the circumference of the washer. -
Spring pins (also called roll pins, tension pins, and expansion pins) are hollow and slotted across the length to facilitate tension. Spring pins are made of carbon spring steel, a pliable yet effective steel ideal for this pin's applications.
Spring pins can be used for many jobs, including electrical connectors in circuits, terminals, actuators, wire harness fixtures, studs, hinges, fixing pulleys or gears to shafts, and more. They permit a wider tolerance than drive pins, taper pins, or collar pins because of their greater flexibility. In addition, the tapered ends of spring pins make them relatively easy to insert and drill. -
Metric Studs
(10)
Studs are mechanical fasteners which are threaded on one or both ends. One end is secured to an object. The other end is used typically with a nut. -
Threaded rod is a fastening bar or rod threaded along its length. Threaded rod is generally produced from cold-rolled steel. Rolled threads offer increased strength, uniform accuracy and a higher degree of surface finish than machine-cut threads, in addition to being lower cost.
Threaded rod can be used with standard nuts and washers and may be used in standard stock lengths or cut by customer to the length required.
