The primary difference is the drive type. A 6-32 cap screw typically has an external hex head (requires a wrench/socket), while a 6-32 socket cap screw has an internal hex drive (Allen key). Both share the same #6-32 UNC thread. Socket cap screws are often used in tight spaces where external access is limited.
We offer carbon steel (grades 4.8, 8.8, 10.9), stainless steel (304, 316), and alloy steel (12.9). For high-corrosion environments, we recommend 316 SS or zinc-nickel coated alloy steel. All materials are sourced from ISO-certified mills.
Our standard MOQ is 5,000 pieces per size. For trial orders or new customers, we accept as low as 1,000 pieces at a small premium. Bulk orders of 50,000+ pieces receive volume pricing discounts.
Production takes 15โ20 days for standard orders. Sea freight to US West Coast ports takes approximately 18โ22 days; to Europe (Rotterdam/Hamburg) about 22โ28 days. Air express (DHL/FedEx) is available for urgent orders in 5โ7 days.
Yes, we offer full OEM/ODM services. We can custom-stamp your logo or part number on the head, apply specific coatings, and package in poly bags, boxes, or blister packs with your branding. No extra tooling charge for orders above 100,000 pieces.
We are ISO 9001:2015 certified. Our 6-32 cap screw products comply with RoHS, REACH, CE and meet ASTM F912 (for socket cap screws). We also provide mill test reports (MTR) and dimensional inspection reports with every shipment.
Absolutely. We provide free samples (you pay shipping) for up to 10 pieces of any 6-32 socket cap screw variant. Sample lead time is 3โ5 days via express courier.
We accept T/T (30% deposit, 70% before shipment), L/C at sight for larger orders, and PayPal/Wise for sample or small orders. For established clients, net 30 terms may be available after credit approval.

"We switched to Boen for our 6-32 socket cap screw supply. The 22% cost savings compared to our previous distributor was immediate. The first batch of 50,000 pieces arrived 3 days early and all passed our thread gauge inspection. Weโve placed 4 repeat orders since."

Henrik Larsson
Technical Director, Nordic Automation AB (Sweden)
"The consistent quality of their 6-32 cap screw is impressive. We use thousands per month in our robotic assembly cells. The zinc-nickel coating holds up perfectly in our harsh environment. Their technical team even helped us optimize the drive depth for automated screwdrivers."

Carlos Mendoza
Supply Chain Manager, Grupo Ferretero del Sur (Mexico)
"Boenโs OEM packaging service was a game-changer. We sell their 6-32 socket cap screw in our own branded boxes across 48 retail locations. The lead time of 18 days from order to our warehouse in Monterrey is unbeatable. Highly recommended for distributors."
