What Boneham & Turner does

Boneham & Turner Ltd is a UK-based, family-owned precision engineering manufacturer founded in 1918 and headquartered in Sutton in Ashfield, Nottinghamshire, with a US subsidiary (Boneham USA). The company designs, manufactures and supplies jig-and-fixture components — drill bushes (plain, headed, serrated, renewable, handle, egg cup and sheet metal anchor types to ISO 4247 / DIN standards), dowel pins (parallel, extractable, solid, tapped and stainless variants to ISO 8734B, ISO 8735B, DIN 6325, DIN 7979), location pins, composite fixings, shims, toggle clamps, hoists and related tooling — alongside distributed Koenig hydraulic sealing plugs and miniature check valves. Sub-brands include Boneham Black Plastic Dowels, Hi-Torque Hex Composite Mould Bushes, PTFE-coated dowels and the Shimpress custom-shim service. Manufacturing is carried out in-house in the UK on conventional precision grinding and CNC equipment, with a recent (December 2024) capacity expansion via a Citizen L220-VIIILFV sliding head lathe.

The business operates a dual-channel sales model: a self-serve e-commerce store on boneham.co.uk sells catalogue items at unit pricing with next-day delivery for orders placed before 14:30, supported by a stockholding of 350,000+ drill bushes and 1.3 million dowel pins (95% of components available from stock); a direct sales desk handles bespoke and traceability-grade components for aerospace and defence customers. Revenue is generated through one-time sales of catalogue components, tailored solutions and precision special parts. The customer base spans five primary verticals — aerospace, defence, motorsport, automotive and general engineering — with aerospace and defence revenues contingent on maintaining AS9100D (EN9100:2018) quality certification and JOSCAR supply-chain accreditation, both of which are held.

Go-to-market combines trade-show presence at Advanced Engineering (NEC Birmingham), Southern Manufacturing and Electronics, DPRTE and Plantworx, with content marketing, newsletters and educational outreach (West Notts College T-Level placements, apprenticeship programme, University of Wolverhampton Racing sponsorship). The company employs 101–250 staff, is privately held with no external venture, private equity or public ownership, and remains under family stewardship following the death of founder figure John William Boneham on 16 July 2025.

Recent moves6 records

Expansion highlights5 records

Broad incumbents

• Würth Group: World's largest fastener and assembly consumables distributor with extensive UK operations. Comparable on threaded components and broad inventory offering, though skewed toward maintenance rather than aerospace-grade precision tooling.
• McMaster-Carr: US-headquartered industrial supply giant with an exceptionally broad catalogue that includes drill bushings, dowel pins, locating components, shims, and toggle clamps. Competes on stock breadth and next-day fulfilment rather than aerospace specialisation, but directly overlaps Boneham's standard catalogue SKUs.
• Kennametal: Public US tooling and industrial materials company serving aerospace, defence, and automotive with metalworking solutions including toolholders and workholding. Same end-customers as Boneham, broader portfolio, with overlap in fixture-grade tooling components.
• RS Components: Major UK and European industrial catalogue distributor carrying locating pins, shims, toggle clamps, threaded plugs, and similar Boneham-adjacent SKUs. Competes on breadth, stock, and next-day delivery rather than aerospace specialisation.
• Bossard Group: Global fastener and assembly solutions provider serving aerospace, defence, and automotive OEMs. Comparable on threaded/fastener side of Boneham's portfolio and on aerospace/defence certification requirements, but a much broader assembly-solutions scope.
• MSC Industrial: Large US metalworking and industrial supply distributor with significant tooling, workholding, and fastener offerings. Overlaps with Boneham on drill bushings, clamps, and locating products sold into similar B2B engineering customers.

Emerging players

• Festo: Global automation, pneumatics, and positioning components supplier with extensive locating-pin and standard-part catalogues. Overlaps with Boneham on locating/positioning components but is much larger and more automation-system focused.

Direct peers

• Carr Lane Manufacturing: US-based manufacturer of jig and fixture components including drill bushings, dowel pins, locating pins, toggle clamps, and fixture clamps. The most direct functional peer to Boneham across product range, specification (ISO/DIN equivalents), and end markets.
• Misumi: Global configurable-components platform selling drill bushes, dowel pins, locating pins, and a deep catalogue of jigs and fixtures online with short lead times. Direct peer on product set, online ordering model, and aerospace/automotive customer profile.
• Accu (Accu Ltd): UK-based e-commerce supplier of precision components including dowel pins, locating pins, threaded fasteners, and shims. Closely matches Boneham's product range and B2B catalogue-led GTM, with overlapping aerospace, motorsport, and general engineering demand.
