One where our 2D thoughts are turned into 3D realities and where you have full control of your creative experiments, with a little help from an online expert community that loves to share what we do. Read more about the condition New: A brand-new, unused, unopened and undamaged item in original retail packaging (where packaging is applicable). The flexibility of our inserts enhances load bearing capacity by deflecting the residual forces into a helical direction, which is dispersed into the wall of the tapped hole. These threaded inserts feature a knurled outer diameter with expansion slots that prevent rotation or loosening due to vibration and ensures consistent self-locking pressure on the fixing screws.This amount includes seller specified domestic postage charges as well as applicable international postage, dispatch, and other fees. Our screw locking inserts have all of the advantages of a free running type plus the additional benefit of prevailing locking torque, which makes them a valuable and reliable choice for use in applications subject to cyclic vibration or impact.

Once fitted, the action of the radial pressure between the insertï¾’s coils and flanks of the tapped hole holds them in place securely. Threaded expansion inserts are designed to provide strong reusable threads in thermoset and other hard plastics and are commonly used in plastic casings and housing. On removal of the male thread, the locking coil relaxes to its original form, allowing for repeated assembly whilst retaining a measurable level of prevailing torque. Internal Thread Size (d) M4 (4mm) Length (L) 8mm Manufacturing Standard Not Standardised Material Stainless Steel (A2) Material Specification Stainless Steel (A2) Metric or Imperial?RS PRO have a great range of threaded inserts made from various materials including brass and steel with zinc plated finishes.

Note: It is recommended that only close fit plated or lubricated bolts and screws are used with screw locking inserts. Constructed from environmentally-sound brass for enhanced strength and resilience, this assortment kit is designed to offer even force distribution and long-term usage.

Self Tapping Inserts have the added benefit of reducing wear within machinery which requires frequent clamping and unclamping. Threaded inserts are designed to be placed into existing holes to provide a threaded receptacle so that screws, bolts or other fixings can be installed. You can change your choices at any time by visiting Cookie preferences, as described in the Cookie notice. Our standard free running wire thread inserts are produced from Austenitic Stainless Steel wire (304/A2 Stainless), which is cold drawn (profiled) to form a diamond-shaped wire.

With Reinforced Threaded Inserts we also offer a version with a stronger cross-section for use in applications with greater stress. New: A brand-new, unused, unopened and undamaged item in original retail packaging (where packaging .The locking torque is achieved by the action of a polygonal grip coil in the insert that exerts radial pressure on the male thread, with each grip coil consisting of a number of tangential locking chords that protrude inside the minor diameter of the normal free running coils. Expansion inserts are ideal for plastics which can resist the expansion of the insert but also flexible to let the knurls anchor into the material. Larger in diameter than the tapped hole, the insert is compressed during installation to ensure maximum surface contact between the flanks of the wire insert and tapped threads. When installed, the threaded inserts, therefore, provide incredible traction and high tightening and loosening torque. The high performance internal thread provided by our wire inserts is far stronger than most parent materials, and is also heat, corrosion, and wear resistant too.
