Captive Bolts & Ceiling Anchor Bolt | Factory
Eliminate supply chain risk, reduce total cost of ownership by up to 37%, and receive ISO-certified captive bolts & ceiling anchor bolts delivered to your door in 15โ25 days. Trusted by 30+ countries in automotive, construction, and heavy machinery.
Switching suppliers mid-project creates hidden costs: requalification, delayed shipments, and rejected batches. A 2025 industrial procurement study found that unplanned supplier changes add 22% to total cost of ownership for fastener buyers.
In overhead lifting and suspended ceiling applications, thread stripping is the #1 failure mode. Low-quality ceiling anchor bolts from non-certified sources cause 26% of field failures in construction, leading to costly rework and safety hazards.
Split shipments, partial container loads, and unpredictable lead times from small factories inflate logistics. Our consolidated factory-direct model cuts freight cost per unit by 30% compared to trading companies.
Non-compliant captive bolts can delay entire projects. 43% of procurement managers report at least one rejected shipment per year due to missing or forged certifications. We provide full traceability and original certificates.
When technical directors receive fasteners that donโt match specs, re-engineering and redesign costs spiral. One mismatched captive bolt can trigger a $50,000+ delay in assembly line integration.
Most factories demand MOQs of 10,000+ units. For ceiling anchor bolts in niche sizes, this forces excess inventory that ties up 15โ20% of working capital. We offer flexible MOQs scaled to your real demand.
Since 2010, Handan Boen Fastener has supplied 30+ countries with precision-engineered fasteners. We are not a trading company โ we are the factory. That means direct pricing, full quality control, and engineering support from material selection to final packaging.
Manufactured to ISO 898-1, ASTM A193, and DIN 6921 standards. Available in carbon steel, stainless steel 304/316, and alloy steel. Retainer plate design ensures the bolt stays captive even under vibration โ ideal for automotive chassis, industrial machinery, and panel assemblies.
Engineered for suspended loads, overhead track systems, and seismic bracing. Compliant with EN 795, ASTM F1554, and ICC-ES AC10. Each batch undergoes tensile testing, proof load verification, and wedge testing to guarantee safety margins above 1.5:1.
Need a non-standard thread pitch, unique head marking, or special coating (Dacromet, Geomet, HDG, Xylan)? Our in-house toolroom delivers prototypes in 5โ7 working days and production runs with full PPAP documentation.

Real feedback from technical directors, purchasing managers, and operations leaders who use our captive bolts and ceiling anchor bolts daily.

"We switched to Boen for our ceiling anchor bolts after repeated thread failures from our previous supplier. Zero failures in 18 months. Their MTRs are always accurate, and lead times are consistently 18 days."

"The captive bolts we ordered for our modular panel system required strict tolerances on the retainer ring. Boen delivered within spec, and the 10.9 grade strength exceeded our requirements. Cost savings of 31% vs. our European supplier."

"We needed a custom ceiling anchor bolt with a unique thread length for seismic bracing. Boenโs engineering team delivered prototypes in 6 days. The full production run of 12,000 pieces was completed in 20 days. Flawless quality."

"Boenโs captive bolts are now standard on all our overhead door assemblies. The consistent thread engagement and plating quality are better than what we got from Germany. Plus, DDP delivery to Dubai in 22 days."
A captive bolt features a retainer plate, shoulder, or spring mechanism that prevents the bolt from being fully removed when loosened. This is critical in automotive, aerospace, and machinery applications where loose fasteners could cause jamming, safety hazards, or component damage. Standard bolts lack this retention feature.
Our ceiling anchor bolts are tested to EN 795 and ASTM F1554. For example, a Grade 8.8 M12 ceiling anchor bolt has a working load limit (WLL) of approx. 1,200 kg in solid concrete (C25/30). We provide pull-out test data and design calculations for every batch upon request.
Absolutely. We offer OEM/ODM customization including customer logos, grade markings, and torque indicators. Our in-house tooling team can create custom heading dies. Minimum order for custom markings is typically 5,000 pieces, but we can discuss smaller lots for trial orders.
Every shipment includes Mill Test Reports (MTR), Certificate of Conformance, and dimensional inspection reports. We also provide CE, RoHS, ISO 9001:2015, and upon request: UL, ABS, Lloydโs, or CCC. Third-party inspection by SGS, Bureau Veritas, or TรV is welcome.
Standard production lead time is 15โ25 working days from order confirmation. For emergency orders, we can expedite to 10 working days for an additional 8% rush fee. Sample orders (up to 50 pcs) are shipped in 5โ7 working days.
Yes, we provide free samples (up to 5 pieces) for qualified buyers. You only pay for shipping. We also offer paid samples with full production intent โ the sample cost is deducted from your first order. Contact us at shuan@fastenboen.com.
We follow a 3-stage QC process: (1) Incoming raw material inspection, (2) In-process inspection (every 500 pieces), and (3) Final random sampling per ANSI/ASQ Z1.4 Level II, AQL 1.0. Customers can request 100% inspection for critical applications at a nominal fee.
