Industrial Supply & MRO Sourcing
Fasteners, hardware, adhesives, sealants, lubricants, abrasives, tools, safety products, facility supplies, raw materials, and catalog-referenced maintenance consumables sourced from U.S. channels.
How industrial supply & mro requirements are handled
MRO requirements are the lines international buyers most often struggle to place economically: a hundred fasteners, two tubes of sealant, a box of abrasives, and a safety item — each too small to justify its own international order, all needed on the same maintenance date.
H&H handles these as ordinary RFQ lines. Small catalog-referenced items can be quoted alongside manufacturer-specific industrial spares and, where eligible, combined into one export-ready shipment with the rest of the requirement.
McMaster-Carr is a U.S. industrial distributor and catalog source, not a manufacturer, and is referenced here only because its catalog numbers are a precise way for a buyer to describe an item. H&H is not an authorized distributor, reseller, representative, or affiliate of any source named on this page.
Major product groups
Fasteners, hardware, and materials
- Bolts, screws, nuts, washers, and threaded rod
- Anchors, pins, retaining rings, and clips
- Structural and mounting hardware
- Bar, sheet, plate, tube, and rod stock
- Plastics, gasket sheet, and engineering materials
Chemicals, lubricants, and abrasives
- Adhesives, threadlockers, and sealants
- Greases, oils, and specialty lubricants
- Cleaners, solvents, and maintenance chemicals
- Abrasives, cutting tools, and finishing products
- Coatings and corrosion protection
Tools, safety, and facility
- Hand tools and precision measuring tools
- Power tool accessories
- Personal protective equipment and safety supplies
- Lockout/tagout and signage
- Storage, shelving, and facility maintenance products
- Specialized catalog-referenced requirements
These groups are a starting point, not a limit. Sourcing is driven by the manufacturer and part number you supply, so requirements outside this list are welcome.
What each line item should include
Every quotation is built from the information you supply. Exact part numbers, suffixes, configurations, specifications, quantities, end use, and destination can all affect what can be sourced and whether it is eligible for export.
Submit your exact part numbers for review — H&H does not select, substitute, or approve components on the buyer's behalf.
- Catalog number or manufacturer part number where one exists
- Clear written description where no catalog number is available
- Material, grade, and finish (for example stainless grade, zinc plating, black oxide)
- Dimensions, thread size, thread standard (imperial or metric), and length
- Pack size versus piece count so quantity is unambiguous
- Applicable technical specification or standard where required
- Safety data sheet requirements for chemicals and lubricants
- Destination country, delivery city, and required delivery window
What most often delays industrial supply & mro quotations
Most quoting delays on this category are information problems rather than sourcing problems. Addressing the points alongside in your first message usually removes a full round trip.
- Quantity given in packs on one line and pieces on another
- Thread standard unstated on fastener lines
- Grade or finish omitted, leaving several valid catalog numbers
- Chemical products requested without checking destination shipping restrictions
- Descriptions supplied without dimensions where no catalog number exists
- Raw material requested without specifying tolerance, temper, or cut length

Dedicated sourcing pages relevant to this category
Brand names are used only to identify the items buyers describe. Sourcing channels are confirmed per requirement, and H&H does not disclose upstream suppliers.
Multi-manufacturer requirements on one quotation
International buyers rarely need only one brand. A single RFQ can combine several manufacturers in this category with lines from other categories, coordinated by one U.S.-based team. See Multi-Vendor Consolidation for how eligibility is determined.
- Small MRO items are quoted on the same RFQ as manufacturer-specific industrial spares.
- Eligible lines are combined into one commercial quotation and, where practical, one consolidated shipment.
- Buyers avoid placing many small international orders across separate U.S. sources.
- Hazardous or restricted items may need to ship separately from general cargo.
Documentation and origin considerations
- Commercial invoice and packing list prepared from the part numbers and quantities you confirm.
- Country of origin is reported only as documented by the supplying source — H&H does not assign or certify origin.
- Export eligibility can depend on the exact part number, configuration, end use, end user, and destination country.
- Destination-country import duties, standards, and clearance requirements remain the buyer's responsibility.
- Chemicals, aerosols, and lubricants may be restricted or require dangerous-goods handling depending on the transport mode and destination.
How a requirement moves through H&H
Submit manufacturer, part number, quantity, and destination on the RFQ form. The category is carried through with your request.
Our U.S. team investigates each line through established channels and returns clarifying questions where needed.
Eligible lines are presented on one quotation with the commercial terms applicable to your destination.
On order, compatible items are consolidated and documentation is prepared for shipment.
