Captive screws are fasteners which remain attached to a panel or parent material, even after they are disengaged from the mating panel or part. They meld with the parent via cold forming, and then fuse with the panel or part into a single entity

Screws are fasteners that consist of a threaded shaft at one end and, typically, a head at the other. They are inserted into solid materials and secured via rotation

Shoulder screws are fasteners with an unthreaded shank. The unthreaded shank is long when compared to its threaded portion, which is located under the head. Shoulder screws can be used to attach one machine part to another, or as a plain bearing in places where rotary or sliding motion is required

Self-sealing fasteners have an elastomeric insert or captive O-ring that simultaneously provides sealing and locking

Nuts are fasteners that are designed to fit around and secure a bolt or screw. The application determines the type of nut to use. 

Electronic fasteners and hardware are small components for spacing or positioning electronic devices on printed circuit boards.

Hose clamps and band clamps are used to secure pipe, hose, tubing and mating circular parts together. Parts include worm drive hose clamps and profiled v-band clamps.

Solenoid valve connectors are used to connect solenoid valves and pressure switches.

Ball screws, lead screws, and ACME screws are used to convert rotary motion or torque into thrust or linear motion

Screw machine shops manufacture screws and other turned or threaded parts from barstock made of various materials

Industrial screwdrivers and screwfeeders are automated tools that are used to turn screws while providing close control of screw torque. They can be electric or pneumatic and may include features such as torque feedback and controlled stopping

Captive fasteners meld with the material into which they are joined through a process known as cold forming. Once joined, the fastener and the material are permanently fused into a single entity

Screw pumps are rotary, positive displacement pumps that have one or more screws to transfer fluids or materials along an axis. 

Feed screws (feedscrews) are horizontally-oriented screws or augers placed in the bottom of a bin, silo, extruder, hopper, or molding machine to provide uniform flow. As the feed screw turns, process material is dispensed

Swiss screw machining produces a high quality finish comparable to ground finishing.  This service is used when high-finish close tolerance bearing surfaces are required on small shafts.
