Why Fastener Manufacturers Need Coverage Built Differently
A fastener that fails in a critical application can cause harm well beyond the part’s own value. That downstream liability severity is exactly what separates fastener product liability coverage from general fabricated metal work, which is why fasteners are underwritten as their own distinct category, not folded into a broader metalworking policy.
Coverage for a Distinct Category Within Metal Manufacturing
Manufacturing Insurance Group insures fastener manufacturers (NAICS 332722, Bolt, Nut, Screw, Rivet, and Washer Manufacturing), the cold-heading, threading, and forming operations that produce the bolts, nuts, screws, rivets, and washers that hold everything else together. Fasteners are underwritten as their own distinct category, not folded into general fabricated metal work, and your coverage should reflect that.
The reason is straightforward. A fastener that fails in a critical application, a structural assembly, a vehicle, a piece of industrial equipment, can cause harm well beyond the part’s own value. That downstream liability exposure is what separates fastener manufacturing underwriting from general metal fabrication, and it is why we place this coverage with carriers who understand the distinction.
If part of your operation also involves buttons, snaps, pins, or needles for apparel, that is a genuinely different manufacturing category (NAICS 339993) with its own classification, and we can help make sure your policy reflects your actual product mix correctly.
If fasteners are one part of a broader metal fabrication operation, see our fabricated metal manufacturing insurance page for coverage across your full production line.
Our Coverages
Fastener Manufacturing Insurance Coverage Options
General Liability Insurance
A visitor is injured touring your production floor. A delivery driver is hurt during a pickup. General liability protects your fastener manufacturing business from third-party bodily injury and property damage claims tied to your premises and operations, separate from any claim involving a fastener after it ships.
Commercial Property Insurance
Cold-heading machines, thread-rolling equipment, and heat-treatment and plating lines represent significant capital investment. Commercial property insurance protects your facility, equipment, and finished inventory against fire, storms, theft, and other covered losses.
Product Liability Insurance
This is the coverage that matters most for fastener manufacturers. A bolt fails in a structural or mechanical application and causes downstream harm well beyond the part’s own value. Product liability provides critical protection against these claims, reflecting the real severity gap between a failed fastener in a routine application and one in a critical assembly.
Business Interruption Insurance
A fire or major equipment failure can halt production for weeks while specialized cold-heading or plating equipment is repaired. Business interruption insurance replaces lost income and covers ongoing expenses while you get back to full production.
Workers Compensation Insurance
High-speed cold-heading, threading, and plating operations all carry real injury risk. Workers compensation is required in nearly every state and covers medical costs and lost wages when an employee is hurt on the production floor.
Supply Chain Insurance
Steel, alloy, and specialty metal supply can be disrupted by everything from mill slowdowns to shipping delays. Supply chain insurance covers financial losses when a vendor failure or material shortage stops your production through no fault of your own.
Errors and Omissions Insurance
Custom fastener specifications for OEM customers carry real professional exposure if a tolerance, material spec, or plating requirement is missed. E&O insurance covers claims arising from those professional mistakes, separate from a product defect claim.
Equipment Breakdown Insurance
Cold-heading presses, thread rollers, and heat-treatment furnaces are expensive and highly specialized. Equipment breakdown insurance covers the internal mechanical and electrical failures a standard property policy excludes, paying for repairs and the income you lose while equipment is down.
Directors and Officers Insurance
A serious product liability claim tied to a critical-application failure can quickly become a leadership-level issue. D&O insurance protects your executives and board from personal liability tied to management decisions during exactly that kind of event.
Employment Practices Liability
Wrongful termination claims, discrimination allegations, and wage disputes carry the same real cost for a fastener manufacturer as any other business. EPLI covers the legal defense and settlement costs tied to employment-related claims from your team.
Why Fasteners Are Underwritten Differently Than General Metal Work
In practice, this means a fastener manufacturer supplying general hardware or consumer goods carries a meaningfully different product liability rating than one supplying structural, automotive, or aerospace assemblies, even when the parts look identical on a shelf. Carriers price around where your fasteners actually end up, not just what they are.
Manufacturers supplying aerospace customers face a real, documented example of this. AS9100 certification, required to supply MS and NAS aerospace fasteners, mandates full lot traceability across raw material, process step, inspection, and test. That level of documentation exists precisely because of how much can go wrong if a single fastener fails in a flight-critical application, and it is a real factor we account for when placing coverage for aerospace-supplying fastener manufacturers.
Manufacturing Insurance Group has placed coverage for manufacturers across dozens of specialized industries for more than 20 years, including the general fabricated metal manufacturers we also work with. If your operation spans both categories, we build one coordinated program instead of forcing your fastener line into coverage designed for something else.

Frequently Asked Questions About Fastener Manufacturing Insurance
Why is fastener manufacturing insured differently from general fabricated metal manufacturing?
Fastener manufacturing carries its own classification because a failed fastener in a critical application, a structural assembly, a vehicle, industrial equipment, can cause harm well beyond the part’s own value. That downstream liability severity is what separates fastener underwriting from broader fabricated metal work, which is why it is priced and structured as its own category rather than folded into a general metalworking policy.
What is the difference between fastener manufacturing and button or notion manufacturing for insurance purposes?
These are genuinely different manufacturing categories with different classification codes. Industrial fastener manufacturing, bolts, nuts, screws, rivets, and washers, falls under NAICS 332722. Buttons, snaps, pins, and needles for apparel fall under a separate code, NAICS 339993, with its own distinct risk profile. If your operation makes both, your policy should reflect your actual product mix accurately.
Why does product liability matter more for fastener manufacturers than general liability alone?
General liability covers injuries and property damage tied to your premises and operations. It does not cover a fastener that fails after it leaves your facility and causes harm in a downstream application. Product liability is the coverage that addresses that exposure, and it is the single most important line for a fastener manufacturer given how much can go wrong if a critical fastener fails.
Is workers compensation required for fastener manufacturers?
In nearly every state, workers compensation is required once you have employees. Cold-heading, thread-rolling, and plating operations all carry real injury risk, and workers compensation covers medical costs and lost wages when an employee is hurt.
What does fastener manufacturing insurance typically cost?
Cost depends on your revenue, product mix, the criticality of the applications you supply, claims history, and coverage limits. Small to mid-size manufacturing operations broadly run between $3,000 and $25,000 a year for a core coverage package, though fastener manufacturers supplying critical applications may see higher product liability premiums reflecting that exposure. A custom quote is the only accurate way to know your real cost.
