Procurement and engineering teams tell us these frustrations every week. Do any sound familiar?
Low-grade 1 socket head cap screw batches fail torque tests, causing 22% rework rates on assembly lines. That kills your margin.
A 10 24 allen head screw from a non-certified supplier often varies ยฑ0.08 mm in pitch diameter. That means field failures and compliance headaches.
Split shipments, wrong surface treatments, and 45-day delays are normal with brokers. Your operations team can't afford that downtime.
Missing CE, RoHS, or ASTM A574 certifications can block your entire shipment at customs. 35% of import delays are fastener-related documentation issues.
๐ You don't need a cheaper screw. You need a reliable supply partner.

Q: What is the difference between a 1 socket head cap screw and a 10 24 allen head screw?
A: A 1 socket head cap screw typically refers to a metric or inch-sized fastener with a cylindrical head and hex socket drive, available in various diameters. A 10 24 allen head screw is a specific US customary thread size (#10-24 UNF) with an Allen (hex) drive. Boen offers both in multiple grades and materials.
Q: What is the minimum order quantity (MOQ) for 1 socket head cap screw?
A: For standard sizes (M3โM20), our MOQ is 500 pcs per size. For non-standard or custom specs, MOQ is typically 2,000 pcs. We offer free samples for qualification before bulk orders.
Q: Do you provide certificates of conformity for 10 24 allen head screw shipments?
A: Yes. Every shipment includes a Mill Test Certificate (MTC) and Certificate of Conformance per ISO 10474. Additional third-party inspection (SGS, TรV) can be arranged at cost.
Q: What surface treatments are available for 1 socket head cap screw?
A: We offer black oxide, zinc plating (clear/yellow/blue), hot-dip galvanizing, Dacromet, phosphate, and nickel plating. For 10 24 allen head screw in outdoor applications, we recommend zinc-nickel or Dacromet for corrosion resistance.
Q: How do you handle international shipping and logistics?
A: We ship via FedEx, DHL, UPS, sea freight (FCL/LCL), and air freight. We handle all export documentation, including customs clearance support. Delivery to USA/Europe typically takes 7โ12 days (air) or 25โ35 days (sea).
Q: Can I get custom laser marking on the 10 24 allen head screw?
A: Absolutely. We offer laser marking, stamping, and roll marking for brand logos, grade marks, and batch numbers. Custom marking is available for orders above 5,000 pcs.
Q: What payment terms do you accept?
A: We accept T/T (30% deposit, 70% before shipment), L/C, and PayPal for sample orders. For established partnerships, we can discuss net 30 or net 60 terms subject to credit approval.
Q: How do you ensure the quality of 1 socket head cap screw during mass production?
A: We follow a 3-stage QC process: (1) Incoming raw material testing, (2) In-process dimensional and hardness checks every 2 hours, (3) Final inspection per ANSI/ASME or DIN standards with AQL 0.65 sampling. Reports are shared with each shipment.
