Stop overpaying for inconsistent fasteners. Boen Fasteners delivers ISO-certified, high-tensile strength socket cap screws engineered for demanding industrial applications. Cut procurement costs by up to 37% with zero quality compromise.
Why pay 40-60% more for the same grade? Major brands add huge margins for standard 5 socket head cap screws. Your supply chain is leaking budget.
Stripped threads, incorrect hardness, and coating failures lead to costly downtime and rework. A single bad batch of 6-32 allen head screws can halt a production line.
Waiting over a month for standard fasteners is unacceptable. It slows down projects and forces costly emergency purchases. Our stock is ready to ship.
Forced to order 10,000+ pieces per size, tying up capital and warehouse space. Flexible MOQs are critical for lean inventory management.
Managing different suppliers for different specs increases administrative overhead and risk. Consolidate your sourcing with a trusted factory partner.
We combine German engineering precision with China's supply chain efficiency.
No middlemen. No markups. Pay only for the metal and labor. Save 30-50% compared to distributor prices.

"Boen's 6-32 allen head screws reduced our assembly line torque variance by 15%. Their factory-direct model saved us 30% annually on our fastener spend."

"We switched to Boen for our 5 socket head cap screws. The consistency in heat treatment and threading is outstanding. Zero failures in our last 50,000 units."


The primary difference is the thread size. A #5 socket head cap screw is typically a smaller diameter metric/imperial size, while a #6-32 UNC is a specific United States Unified Thread Standard (UNC) size with 32 threads per inch. Both utilize an allen key drive. We stock both in various grades and materials.
We offer 10.9 and 12.9 grade alloy steel, 304 (A2) and 316 (A4) stainless steel, and brass. High-tensile 12.9 grade is ideal for high-stress applications. We can also provide specialized coatings like black oxide, zinc plating, or hot-dip galvanizing.
Absolutely. We specialize in OEM/ODM orders. You can specify custom lengths, drive depths, and coatings (e.g., zinc-nickel, PTFE). Our minimum order quantity for custom 6-32 allen head screws is typically 5,000 pieces, depending on complexity.
For standard sizes and materials (e.g., M6 x 20mm, 10.9 grade), our MOQ is flexible. We can start with as low as 1,000 pieces for sampling. For bulk production pricing, we recommend rolling orders of 10,000+ pieces per size.
We are ISO 9001:2015 certified. Our QC process includes raw material chemical analysis, hardness testing, tensile strength testing, and dimensional inspection using optical comparators. A full inspection report (COA) is provided with every shipment.
We offer FOB Tianjin/Xingang, CIF to major ports (Los Angeles, Hamburg, Rotterdam), and DDP (Delivered Duty Paid) for USA and EU customers. Standard sea freight takes 25-35 days. Express air freight (DHL/FedEx) takes 7-10 days.
Yes, we provide free samples for qualified buyers. You just pay the shipping cost. We can send a sample kit including various sizes of 5 socket head cap screws and 6-32 allen head screws for your evaluation.
