You are not just buying a screw โ you are buying reliability, downtime, and safety. Here is what we hear every day from procurement and engineering leaders:
Distributor markups of 35โ50% on standard 10-32 cap screws are common. You pay for layers that add no value.
Batch-to-batch variation in thread fit and hardness leads to assembly failures and warranty claims. 17% of field returns in industrial equipment trace back to fastener defects.
Split shipments, slow sea freight, and surprise duties. Our customers save 22โ30% on landed cost with consolidated factory-direct orders.
Missing CE, RoHS, or ISO docs can delay your project. We deliver full documentation with every shipment โ no chasing, no delays.
๐ You deserve a supplier that treats fasteners as engineered components, not commodities.
We are not a trading company โ we are the manufacturer. Since 2010, we have shipped over 280 million fasteners to 30+ countries. Here is how we deliver value:

Our 10-32 hex head cap screws are used in tractor assemblies, harvesters, and irrigation systems. Grade 10.9 ensures vibration resistance in high-stress field conditions.
Flat head socket cap screws for brake assemblies, engine brackets, and interior modules. 316 stainless for corrosion resistance in under-hood environments.
Robotics and conveyor systems demand precision. Our 10-32 flat head socket cap screws provide flush mounting with zero protrusion โ critical for safety and alignment.
Compact 10-32 flat head screws for rack-mount servers, control panels, and telecom cabinets. Black oxide finish for a professional look and corrosion protection.
๐ Key Performance Data: In a recent 12-month field study, Boen 10-32 hex head cap screws showed zero fatigue failures in high-vibration pump applications โ outperforming two major branded alternatives.

๐ธ Instant quotes, order confirmations, and shipping updates โ all in real time.
The flat head version has an 82ยฐ countersunk head with a hex socket drive, designed for flush mounting. The hex head version has an external hexagon head, ideal for applications where clearance is not an issue and higher torque is needed. Both share the same #10-32 UNF thread.
We stock 304 (A2) and 316 (A4) stainless steel. 316 offers superior chloride resistance for marine and chemical environments. All material is fully traceable with mill certificates.
Yes. We can produce custom lengths, drive types, and coatings including zinc-nickel, PTFE, Dacromet, and hot-dip galvanized. Minimum order quantity (MOQ) for custom runs is typically 5,000 pcs. Contact us for a quote.
Standard lead time is 15โ20 days from order confirmation. For urgent orders, we offer 7โ10 day express production. We ship via FOB, CIF, or DDP โ air freight (5โ7 days) or sea freight (20โ35 days).
We follow a 3-stage QA process: incoming material inspection, in-process dimensional checks (optical comparators, thread gauges), and final sampling per AQL 2.5. Our lab tests hardness, tensile strength, and salt spray resistance.
We accept T/T (bank transfer), L/C (letter of credit), and PayPal for small orders. For first-time clients, we typically require 30% deposit and 70% against copy of B/L.
Yes. We offer free samples for qualified buyers (you pay shipping). Samples are available in standard sizes and finishes. Contact us with your requirements.
Absolutely. We support blanket order agreements with scheduled releases, and can provide standard EDI or CSV formats for ERP integration. We also offer kanban / VMI programs for high-volume customers.
โWe use Boenโs 10-32 flat head socket cap screws in our robotic arms. The quality is flawless โ every batch passes our torque and hardness tests. Their team is responsive and professional.โ
Liam O. โ Robotics Engineer, Dublin, IrelandโWe switched 80% of our fastener spend to Boen. The cost savings are real โ about 27% lower than our previous supplier. Their 10-32 hex head cap screws are now our standard.โ
Marta S. โ Procurement Lead, Barcelona, SpainโThe documentation Boen provides is world-class. Full traceability, CE declarations, and material certs โ exactly what our compliance team needs. Highly recommended.โ
