M10 Socket Screw & M10 x 1.25 Socket Head Cap Screw | Maker
Cut your fastener costs by up to 37% without compromising on tensile strength, thread accuracy, or delivery speed. Designed for industrial buyers, technical directors, and procurement teams who demand ISO-certified, factory-direct M10 socket screws with full traceability.
“We saved $0.03 per unit – then lost $12,000 in rework.” – Procurement Manager, German automotive tier-2 supplier
A major US agricultural OEM reported 18% field failure rate on imported M10 x 1.25 socket head cap screws. Root cause: inconsistent thread pitch and poor heat treatment. Total recall cost: $470,000.
Split shipments from multiple suppliers increase your total landed cost by 12–22%. One PO, one factory, one incoterm – that’s what cuts your TCO.
Without ISO 898-1 and RoHS compliance, your M10 socket screws can’t enter European automotive or medical supply chains. One missing certificate = entire container rejected at customs.
A batch of M10 x 1.25 socket head cap screws from a non-integrated supplier showed HRC 22–38 variance. Your torque specs become meaningless. You need HRC 32–36 every time.
We don’t just sell fasteners – we engineer joint reliability into every M10 x 1.25 socket head cap screw that leaves our factory.
From raw material incoming inspection to thread rolling, heat treatment, and final sorting – all under one roof in Handan, China. No middlemen, no quality drift.
Our M10 x 1.25 socket head cap screw maintains 6g thread tolerance with a pitch deviation below 0.02 mm. Verified by Zeiss CMM and optical thread scanners.
Controlled atmosphere carburizing + oil quenching delivers ±2 HRC batch-to-batch. Full JIS G4105 / SAE J429 Grade 8 compliance.
Our OEM/ODM workflow allows custom M10 socket screw lengths, head markings, and coatings (Dacromet, Geomet, Zinc-Nickel) with a typical lead time of 12–18 working days.
Every batch of M10 x 1.25 socket head cap screw comes with a Material Test Certificate (MTC) per EN 10204 3.1. Heat number, hardness curve, and dimensional report included.
We ship FOB, CIF, or DDP to ports in Rotterdam, Hamburg, Los Angeles, and Singapore. Average transit: 22–28 days to Europe, 18–24 days to US West Coast.

Three industries, three performance benchmarks – one fastener.

A Dutch harvester manufacturer replaced their previous supplier with our M10 socket screw (Grade 12.9, Geomet coating). Result: zero thread failures in 18 months vs. 6% annual failure rate previously. €0.09 per unit savings.

A Spanish tier-1 supplier uses our M10 x 1.25 socket head cap screw in engine mounting brackets. 99.97% on-line torque acceptance rate. Batch-to-batch hardness variance < 2 HRC. 15% reduction in rework cost.

A UK-based steel frame contractor switched to our M10 socket screw for cladding rail fixings. DDP delivery to site, mixed pallet kitting. 22% lower total landed cost vs. previous German supplier.

“We tested 4 suppliers for M10 x 1.25 socket head cap screws. Boen’s batch-to-batch consistency was 3x better than the next best. Their MTC reports are accurate, and the 15-day lead time is real. We now use them for 80% of our fastener spend.”

Sarah Chen
Supply Chain Director, MidWest Conveyors (USA)
“We were paying 40% more for a German brand. Switched to Boen’s M10 socket screw – same Grade 12.9, same dimensional accuracy. Saved $68,000 annually on a single SKU. Their DDP service to Chicago is seamless.”

Luca Rossi
Technical Director, Rossi S.p.A. (Italy)
“I’m picky about thread quality. I ran 50 pieces of their M10 x 1.25 socket head cap screw through our optical comparator – zero rejects. The 6g tolerance is genuine. We’ve placed 3 repeat orders in 2025.”

Everything you need to know before placing your first PO for M10 socket screws.
An M10 socket screw refers to any metric M10 fastener with a hexagon socket drive. The M10 x 1.25 socket head cap screw specifies the exact thread pitch – 1.25 mm – which is the fine thread variant. This pitch is common in automotive and vibration-sensitive applications. At Boen, we produce both standard M10 (1.5 pitch) and M10 x 1.25 fine thread versions under the same quality system.
Yes. Our OEM/ODM service allows custom lengths from 16 mm to 200 mm, laser or stamp markings (company logo, grade, batch number), and special coatings. Minimum order quantity for custom M10 socket screws is typically 5,000 pcs per SKU. Lead time: 12–18 working days.
Every batch of M10 x 1.25 socket head cap screw is manufactured under ISO 9001:2015 and complies with ISO 898-1 (mechanical properties), RoHS, and REACH. We provide EN 10204 3.1 MTC with hardness, tensile, and dimensional data. Third-party testing by SGS or TÜV can be arranged.
For standard M10 socket screw sizes (Grade 12.9, zinc-plated), MOQ is 1,000 pcs per size. Lead time: 7–12 working days for stock items, 15–18 working days for coated or custom variants. We ship FOB, CIF, or DDP to your port.
We use a 3-stage inspection process: (1) incoming raw material chemical analysis, (2) in-process hardness and thread gauge testing every 2 hours, and (3) final 100% visual + dimensional sampling per ANSI/ASQ Z1.4. Our Zeiss CMM and optical thread scanners ensure 6g tolerance every time.
For new customers, we require 30% deposit, 70% balance against copy of shipping documents. Payment via T/T, L/C, or Western Union. After 3 successful orders, we can negotiate open terms. Free samples are available – you pay only shipping.
Absolutely. We ship to 30+ countries including Germany, Netherlands, UK, USA, Canada, Italy, and Spain. Our DDP (Delivered Duty Paid) service means you receive the goods at your door with no hidden customs fees. Typical transit: 22–28 days to Europe, 18–24 days to US West Coast.
We stand behind every shipment. If a non-conformance is confirmed via third-party testing, we will replace the entire batch at our cost or issue a full refund. This is part of our Quality Guarantee Program. We’ve maintained a 99.6% on-time, on-spec delivery rate over the past 3 years.
