Products classified under HTS 7318.16.00.85
M8 Hex Nuts Zinc Plated
These are standard M8 hex nuts made from carbon steel with a zinc plating for corrosion resistance, used to secure bolts in machinery and construction. They fall under HTS 7318.16.0085 as 'other' threaded nuts of iron or steel, not specifically classified as machine screw nuts or locknuts. The hexagonal shape and metric threading distinguish them from square or specialty nuts.
Brass-Plated Acorn Nuts 5/16 Inch
Decorative 5/16-18 acorn nuts with brass plating and domed cap hide exposed threads on furniture and automotive trim. They qualify for HTS 7318.16.0085 as 'other' steel nuts, with plating not altering base steel classification. Aesthetic finish makes them popular for visible fasteners.
Heavy Hex Nuts ASTM A563 Grade DH
Heavy pattern hex nuts per ASTM A563 DH specification for high-strength structural bolting in bridges and buildings. HTS 7318.16.0085 covers these as 'other' threaded nuts of alloy steel. Wider across-flats design handles greater loads than standard hex nuts.
Square Nuts 3/8-16 UNC
Forged square nuts with 3/8-16 UNC coarse threads for welding and timber framing applications. HTS 7318.16.0085 includes these non-hexagonal threaded nuts of steel. Square shape prevents spinning during assembly.
Cap Nuts Fine Thread 1/4-28
Acorn-style cap nuts with 1/4-28 UNF fine threads and closed end for protecting bolt ends in exposed assemblies. Steel construction with various finishes; HTS 7318.16.0085 as 'other' nuts. Prevents dirt ingress and improves appearance.
High-Strength Alloy Steel Nuts Grade 9
Grade 9 hex nuts from alloy steel for extreme-duty aerospace and racing applications, matching high-strength bolts. HTS 7318.16.0085 covers alloy steel 'other' nuts. Heat-treated for 150 ksi tensile strength.
Tee Nuts 10mm Press-In
Four-prong tee nuts for press-fitting into wood or particleboard, M10 barrel thread for furniture assembly. Steel construction; HTS 7318.16.0085 as 'other' threaded nuts. Prongs expand to lock securely.
Castle Nuts 1/2-13
Slotted castle nuts with 1/2-13 UNC threads and drilled for cotter pin retention in machinery pivots. Steel with protective finish; HTS 7318.16.0085 'other' nuts. Prevents loosening under vibration.
Bulk Bin Hex Jam Nuts M12
Thin profile M12 hex jam nuts for locking against primary nuts in adjustable assemblies. Carbon steel, various platings; HTS 7318.16.0085 'other' nuts. Lower height allows close spacing.
Deck Nuts Galvanized Hot-Dip
Heavy hex nuts with hot-dip galvanization for coastal construction and deck hardware. Meets ASTM A153 coating specs; HTS 7318.16.0085 steel nuts. Triple-layer corrosion protection.
Precision Ground Finish Nuts
M14 hex nuts with precision ground bearing surfaces for high-accuracy instrumentation mounts. Tool steel construction; HTS 7318.16.0085 'other' nuts. Micrometer-level flatness.
Weld Nuts Projection Type
Projection weld nuts M8 with 3-4 weld projections for robotic resistance welding to sheet metal. Steel with zinc coating; HTS 7318.16.0085 threaded nuts. Ensures consistent weld quality.
Clutch Nuts Slotted
1/4-20 slotted clutch nuts for rapid hand adjustment in machinery clutches and linkages. Malleable iron/steel; HTS 7318.16.0085 'other' nuts. Screwdriver slot enables quick torque adjustment.
Stainless Steel Wing Nuts M6
M6 wing nuts from 304 stainless steel feature thumb-turn wings for hand-tightening without tools, ideal for marine and outdoor applications. Classified under HTS 7318.16.0085 as 'other' threaded nuts due to their unique shape excluding machine or locknut categories. Corrosion resistance suits them for harsh environments.
Nylon Insert Lock Nuts M10
M10 prevailing torque locknuts with nylon insert for vibration resistance in automotive and appliance assembly. Although locking feature, classified under HTS 7318.16.0085 as 'other' nuts if not prevailing torque type per notes. Nylon provides reusable locking without metal deformation.
