The 10mm x 90mm Resin Chemical Internal Socket (JCP Fixings code RCITS10) is a female, internally threaded anchor insert intended to be embedded in a resin (chemical) anchoring system to provide a durable M10 internal thread in concrete, block or masonry. Its primary use is to create a clean, repeatable internal thread for attaching fixtures or for receiving a threaded stud where through-bolting is impractical or where high pull‑out loads are required from a post‑installed connection.

This internal socket is manufactured from carbon steel with a zinc electroplated finish to BS EN ISO 2081 for enhanced corrosion resistance in typical construction environments; A2/A4 stainless steel options to BS EN ISO 3506 are available on request for aggressive or marine atmospheres. The internal thread is ISO metric coarse M10 x 1.5 made to ISO 261 / BS 3643 tolerances so it accepts standard M10 bolts, studs and threaded components. The body length is 90mm overall with a serrated/knurled external profile designed to improve mechanical keying and resin adhesion. As an anchor accessory it is compatible with commonly used vinylester and polyester chemical resin systems; use in accordance with the resin manufacturer’s installation instructions and recommended drill hole and embedment depths.

Typical applications include mechanical and electrical fixings, steelwork connections, balustrade and handrail anchors, façade and cladding fixings, and post‑installation of threaded connections in structural repair and retrofit work. The product is commonly used across construction, civil engineering, plant installation and industrial maintenance where a re‑usable or replaceable internal thread is needed in masonry substrates.

Key benefits are straightforward compatibility with standard M10 fasteners, a robust carbon steel body supplied with corrosion‑protective plating (or stainless options for enhanced resistance), and an external profile optimised for secure resin bonding to deliver reliable load transfer. The designation RCITS10 identifies this 10mm internal socket in the JCP Fixings range.

Duchy Fasteners holds RCITS10 in stock in single items and trade packs; we also stock internal threaded sockets in a wider range of diameters (commonly M8–M16) and lengths—please contact us for available pack sizes and stainless variants.
