Screw Thread Insert Cross Recessed Aluminum Fine Threaded Custom
The screw thread insert is the nut with both internal thread and external thread. It’s usually custom made according to client’s request or drawing. A threaded bushing, also known as a threaded insert, is a fastener element that is inserted into an object to add a threaded hole.screws for mill inserts. Ever Hardware provides the custom-made screw thread insert and customizable packaging.
In applications where vibration or rotation may work a nut loose, various locking mechanisms may be employed: lock washers, jam nuts, specialist adhesive thread-locking fluid such as Loctite, safety pins (split pins) or lockwire in conjunction with castellated nuts, nylon inserts (Nyloc nut), or slightly oval-shaped threads.
The most common shape is hexagonal, for similar reasons as the bolt head – 6 sides give a good granularity of angles for a tool to approach from (good in tight spots), but more (and smaller) corners would be vulnerable to being rounded off. It takes only 1/6th of a rotation to obtain the next side of the hexagon and grip is optimal. However polygons with more than 6 sides do not give the requisite grip and polygons with fewer than 6 sides take more time to be given a complete rotation. Other specialized shapes exist for certain needs, such as wingnuts for finger adjustment and captive nuts (e.g. cage nuts) for inaccessible areas.
Aluminum is a relatively soft, durable, lightweight, ductile, and malleable metal with appearance ranging from silvery to dull gray, depending on the surface roughness. It is nonmagnetic and does not easily ignite. A fresh film of aluminum serves as a good reflector (approximately 92%) of visible light and an excellent reflector (as much as 98%) of medium and far infrared radiation. The yield strength of pure aluminum is 7–11 Mpa, while aluminum alloys have yield strengths ranging from 200 Mpa to 600 Mpa. Aluminium has about one-third the density and stiffness of steel. It is easily machined, cast, drawn and extruded.
