Steel thread inserts can effectively improve screw connection, greatly improving the reliability. Used in all kinds of low strength materials, thread inserts can largely improve the wear resistance performance of screw connection, and avoid thread damage. _x000D_ _x000D_ _x000D_ Features: _x000D_ Steel thread inserts used in low strength materials such as aluminum, magnesium, can avoid thread damage and get a good connection performance, to enhance connection strength and improve connection condition._x000D_ _x000D_ Used for parts that requires frequent removing, it can greatly improve service life and wear-resistance of screw thread. _x000D_ Because of a certain elasticity, thread insert can even the load distribution on each thread, eliminate pitch and tooth deviation between screw and screw hole, and absorb vibration, thus increasing the screw thread connection strength and fatigue resistance. _x000D_ It can prevent screw from getting loose,especially used for products requiring high coefficient of insurance. _x000D_ Easy to maintenance, install a thread insert into a damage screw hole, then the screw hole can be used as normal, in order to avoid workpiece loss. _x000D_ _x000D_ Specification: _x000D_ Material: Stainless steel 304 _x000D_ Size (inner diameter*installed pitch*installed length) & Quantity(Optional): _x000D_ M5*0.8*1 D, 100pcs;_x000D_ _x000D_ M5*0.8*1.5 D, 100pcs;_x000D_ _x000D_ M5*0.8*2 D, 100pcs;_x000D_ _x000D_ M5*0.8*2.5 D, 100pcs; _x000D_ _x000D_ M5*0.8*3 D, 100pcs; _x000D_ Weight: 24g~79g / 0.8oz~2.8oz (approx.) _x000D_ _x000D_ _x000D_ Package list: _x000D_ 1 set * Threaded Inserts _x000D_ _x000D_ _x000D_ Note: Installed length= #D means # x diameter, for example, M5*0.8*1 D has installed length = 1D = 1 x 5 = 5mm.
