Product Information

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.

M4 steel threaded inserts enable you to install a threaded hole in to wooden and composite materials. Threaded inserts with internal hexagon socket for threaded coupling in case when the standard mounting nuts or blind nuts cannot be used. Trusted by engineers all over the world, every part of every RS PRO product has been rigorously tested against demanding industry standards; they’re only given the RS PRO Seal of Approval if we’re confident of their exceptional quality, which means you can be confident too.

Once fitted, the action of the radial pressure between the insertï¾’s coils and flanks of the tapped hole holds them in place securely. It is not possible for us to draw any conclusions about you, and any data collected as a result will never be passed on to third parties.

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? 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. Constructed from environmentally-sound brass for enhanced strength and resilience, this assortment kit is designed to offer even force distribution and long-term usage. A range of expansion inserts suitable for use with most plastic materials, using either through or blind holes.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. Without this type of technology, our Services won't work properly or we won't be able to provide certain features and functionalities.

Reinforced Threaded Inserts are suitable for use in various materials, including light metals and casting. Components in this range are available in A1 Stainless Steel as standard, with Chemical Blackening available.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. With Reinforced Threaded Inserts we also offer a version with a stronger cross-section for use in applications with greater stress. 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. 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.
