โ ๏ธ The Hidden Cost of a โCheapโ Concrete Screw
Every purchasing manager who has sourced 1/4" concrete screws knows the frustration. Here are the five pains that erode your bottom line โ and your sleep.
Distributor Markups Up to 40%
When you buy 1/4 x 1-1/4 concrete screws through a middleman, youโre paying for their warehouse, sales team, and profit margin. A factory-direct source eliminates that entirely.
Inconsistent Hardness & Stripped Heads
Low-grade 1/4 x 2-3/4 concrete screws often fail case-hardening tests. Result? Stripped hex heads, broken shanks, and costly rework on site.
Unpredictable Lead Times (30โ60 Days)
Most traders quote 4 weeks, but delays are common. Our factory runs 3 shifts and ships 90% of orders within 10 working days.
Missing Compliance Certificates
European and US buyers require CE, RoHS, ISO 9001 documentation. Many suppliers canโt provide them. We include full certs with every shipment.
High Freight & Hidden Fees
Consolidated shipping from small suppliers often means 30% higher freight cost per kg. We offer FOB, CIF, and DDP terms with transparent pricing.
โ Why Boen Fastener โ Factory-Direct 1/4" Concrete Screws
Founded in 2010, Handan Boen Fastener Manufacturing Co., Ltd. operates a 50,000 sqm production base in Hebei, shipping to 30+ countries. Here is what makes our 1/4 x 1-1/4 concrete screws and 1/4 x 2-3/4 concrete screws different.
Integrated Production โ One Roof Control
From wire drawing, cold heading, heat treatment to surface plating โ we control every step. No outsourcing, no quality variance.
Case-Hardened to โฅ 55 HRC
Our 1/4" concrete screws undergo through-hardening + surface tempering to achieve a core hardness of 32โ38 HRC and case depth of 0.15โ0.30 mm. No stripping, no brittle failure.
Full Material Traceability (MTC)
Every batch of 1/4 x 2-3/4 concrete screws comes with a Material Test Certificate per EN 10204 3.1. You get the chemical composition and mechanical properties in writing.
Precision Thread Geometry
Thread pitch tolerance 6g (ISO 68-1) ensures consistent engagement with standard concrete anchors and nuts. Reduced installation torque variance by 22% in field tests.
RoHS & REACH Compliant Coating
Trivalent zinc plating (blue/clear/yellow) with โฅ 72h salt spray resistance per ASTM B117. Suitable for indoor and sheltered outdoor use.
10-Day Express Production
Standard lead time: 10โ15 working days for quantities under 500,000 pcs. Express (5โ7 days) available for urgent orders. We keep 20+ tons of 10B21/10B28 wire rod in stock.

Construction Framing
Steel-to-concrete fastening for partition walls, mezzanines, and structural bracing.
Automotive Assembly
Jig and fixture mounting on concrete floors. 1/4 x 1-1/4 concrete screws are ideal for low-profile hold-downs.
Agricultural Machinery
Equipment anchoring in barns, silos, and concrete pads. The 1/4 x 2-3/4 concrete screw provides extra embedment depth.
Electrical & Solar
Mounting cable trays, conduit supports, and solar panel racking to concrete roofs and slabs.

โ Frequently Asked Questions
Q: What is the difference between 1/4 x 1-1/4 concrete screws and 1/4 x 2-3/4 concrete screws?
A: The only difference is length. The 1/4 x 1-1/4 concrete screw (31.75 mm) is used for fastening thinner materials (1โ2 mm steel plate, wood furring strips) to concrete. The 1/4 x 2-3/4 concrete screw (69.85 mm) is for thicker attachments (3โ6 mm steel, double wood layers) or where deeper concrete embedment is required for higher pull-out loads.
Q: What is the minimum order quantity (MOQ) for factory-direct pricing?
A: Our standard MOQ is 10,000 pcs per size. For trial orders, we accept 5,000 pcs at a slightly higher unit price. Contact us for samples โ we offer free samples (you pay freight) for qualified buyers.
Q: Do you provide CE, RoHS, and ISO 9001 certifications?
A: Yes. Every shipment of 1/4 x 1-1/4 concrete screws and 1/4 x 2-3/4 concrete screws includes ISO 9001:2015, CE marking (EN 14592), and RoHS/REACH compliance documentation. Additional certificates (UL, FCC, GS) can be arranged for specific projects.
Q: What payment terms do you accept?
A: We accept T/T (30% deposit, 70% before shipment), L/C at sight, and for established customers, net 30โ60 days (subject to credit approval). We also accept Alibaba Trade Assurance for added security.
Q: How do you handle logistics and shipping?
A: We offer FOB (Tianjin/Xingang), CIF, and DDP terms. For standard orders under 500 kg, we use air freight (3โ5 days) or express courier (DHL/FedEx, 5โ7 days). For bulk orders (1โ20 tons), sea freight is the most economical. We provide full tracking and customs documentation.
Q: Can you customize the head marking or packaging?
A: Absolutely. We offer OEM/ODM services including custom head stamps (your logo, grade marks), special packaging (poly bags, bulk cartons, wooden pallets with shrink wrap), and mixed container loads. MOQ for OEM is 50,000 pcs per size.
Q: What after-sales support do you provide?
A: Every order includes a 12-month warranty against manufacturing defects. If you encounter any quality issues, we provide free replacement or full refund (including freight). Our technical team is available via WhatsApp/email within 2 hours during business hours.

From German automotive Tier-2 suppliers to US construction distributors โ our concrete screws are specified for their consistency and value.
โWe replaced our previous supplier with Boen for 1/4 x 2-3/4 concrete screws. The case hardness consistency is noticeably better โ zero strip-outs in our last 12,000 units. Lead time was 11 days, not the quoted 28.โ
