Thread Inserts — Wire Thread Repair from Recoil
AIMS Industrial stocks Recoil thread inserts covering metric, UNC and UNF thread forms in 304 stainless steel — including tanged free-running, keyserts and left-hand variants.
Whether you're repairing stripped threads or installing permanent thread reinforcement in aluminium, cast iron or soft alloys, Recoil inserts deliver a stronger thread than the parent material. Available in individual packs and multi-pack bulk quantities to suit workshop and production needs.
Types of Thread Inserts We Stock
- Recoil Metric 304 Stainless Steel Inserts: Wire thread inserts for metric threads from M4 to M12+ available in tanged and tang-free (free-running) variants — ideal for general engineering and maintenance repair.
- Recoil UNC & UNF Imperial Inserts: Unified National Coarse and Fine thread inserts in 304 stainless steel for imperial fastener applications in automotive and aerospace-aligned repairs. Available in 5-packs and bulk packs.
- Left-Hand Thread Inserts: Recoil left-hand wire thread inserts (e.g. 9/16-20 LH) for applications where conventional right-hand thread engagement would loosen under load — commonly used in rotating assemblies.
- Keysert Light — Metric Stainless Steel: Recoil Keysert inserts provide a positive locking thread repair for high-stress applications, featuring keys that grip into the parent material to prevent rotation and pullout.
- Bulk Packs & Assortments: Individual inserts available in 5-packs through to 42-packs (e.g. M4 x 0.7 x 2D). Suitable for workshops wanting a ready supply of the most common thread sizes without repeated ordering.
Why Engineers Choose Recoil Thread Inserts
- Stronger than Parent Material: Recoil wire thread inserts create a 304 stainless steel internal thread that exceeds the tensile strength of the host material — especially important in aluminium housings and castings.
- Corrosion-Resistant Construction: 304 stainless steel construction makes Recoil inserts suitable for washdown environments, marine applications and anywhere moisture and chemicals are present.
- Free-Running & Locking Options: Choose free-running inserts for standard fastener re-assembly or locking variants (STI/Keysert) where vibration resistance is critical — applicable across mining, transport and heavy industry.
- Precision Thread Form: Recoil inserts comply with ISO and Unified thread standards — ensuring correct fit with standard metric and imperial fasteners without the need for oversize replacement bolts.
