China-Based Manufacturer Supplying Bolts, Nuts, and Washers in Volume to Global Customers.
Wholesale Supply of Standard Threaded Connection Components
During equipment maintenance, the most common problem is not finding a bolt that appears similar; it is confirming whether that bolt will correctly mate with the existing nut, washer, mounting hole, threaded hole, and assembly position. Standard fastener purchasing requires confirmation of a complete connection relationship, not an isolated product name. As an industrial bolt supplier, industrial nut manufacturer, and industrial washer supplier, LANCIE manufactures and supplies standard threaded connection components and related matching parts in volume.Why is a new bolt that will not fit an existing nut more difficult than simply finding a bolt?
As an industrial bolt supplier, industrial nut manufacturer, and industrial washer supplier, we manufacture and supply standard threaded connection components and related matching parts in volume.
For standard threaded connection components, the key purchasing task is to confirm the bolt, nut, washer, thread, material, and matching relationship as one complete assembly set.
For machinery and equipment manufacturers, we manufacture and supply bolt fastener products in a wide range of specifications. For OEMs, automation equipment manufacturers, engineering project buyers, MRO maintenance buyers, and industrial distributors, we manufacture and supply standard threaded connection components and related matching parts in volume.

We Wholesale Combination Bolts and Screws to Applicable Standards and Specifications.
Fastener standards, threads, and dimensions form the basis for quotation. When requesting a DIN standard bolt quotation, an ISO nut and washer quotation, or a quotation for combination bolts and screws, provide the applicable standard, diameter, length, pitch, thread system, fully threaded or partially threaded requirement, head style, drive type, material, property class, surface finish, and quantity for each specification wherever possible. The factory can confirm project requirements against DIN, ISO, or customer-specified standards.Which standards can be used to confirm hex bolts, nuts, washers, and screws?
The factory can confirm project requirements against DIN, ISO, ANSI, ASME, ASTM, JIS, GB, or customer-specified standards. Hex-head bolts may be reviewed against standards such as DIN 933 and ISO 4017; hex nuts against DIN 934 and ISO 4032; flat washers against DIN 125 or the applicable current equivalent; spring washers against DIN 127 or the applicable project standard; and socket-head cap screws against DIN 912 and ISO 4762. The applicability of specific standards, dimensions, materials, property classes, surface finishes, and matching arrangements remains subject to customer project information and final confirmation.
What specification information should be provided before quotation?

Wholesale Hex Bolts, Flange Bolts, and Socket-Head Fasteners.
Connection Components for Equipment Frames and Mounting Plates.
A set of connection components must be matched before assembly. Sourcing hex bolts, buying flange bolts, hex nuts, flange nuts, flat washers, spring washers, and lock washers does not involve independent auxiliary materials. The thread system, nominal size, material, property class, surface requirements, and connection purpose determine whether they can form a correct matching set.Why must a set of connection components be matched before assembly?
A set of connection components must be matched before assembly. Sourcing hex bolts, buying flange bolts, hex nuts, flange nuts, flat washers, spring washers, and lock washers does not involve independent auxiliary materials. The thread system, nominal size, material, property class, surface requirements, and connection purpose determine whether they can form a correct matching set. For repeated assembly, maintenance replacement, or fixed-component issue kits, confirming the relationship among bolts, nuts, and washers before purchasing can reduce repacking, supplementary purchases, and repeated verification. When diameter, length, pitch, fully threaded or partially threaded requirements, head style, drive type, material, property class, surface condition, quantity, or matching relationship changes, the same product name does not mean that direct replacement is possible.
What bolts, nuts, washers, and screws can be supplied?
The factory manufactures and supplies hex bolts, flange bolts, hex nuts, and flange nuts.
Available matching components may include flat washers, spring washers, lock washers, socket-head cap screws, pan-head machine screws, countersunk machine screws, and set screws. Combination bolts and combination screws may be pre-assembled with flat washers, spring washers, or other specified washer combinations. Bulk purchasing of hex bolts is common for equipment frames, brackets, mounting plates, and general structural connections. As a flange bolt supplier, we can prepare project quotations for applications requiring flange-head bearing surfaces or specified mating conditions. Socket-head cap screws, pan-head machine screws, countersunk machine screws, and set screws may be used in enclosures, panels, fixtures, locating structures, or locations with limited installation space. Metric bolt batch supply, UNC/UNF fastener purchasing, and other specified thread forms must be confirmed against customer standards, specification sheets, drawings, or purchasing information.
Case Study: A Colombian automation manufacturer mixed flange bolts and flat washers
Case Study 2: A Colombian automation manufacturer mixed flange bolts and flat washers, resulting in insufficient preload. After flange-face contact requirements and washer-matching relationships were clarified, the parts were rematched successfully on the first review, followed by a repeat order for 400 parts.
Fasteners in Export Packing and Shipping Cartons for Volume Supply.
Maintenance-Reorder Fasteners Identified by Equipment Model.
Industrial fastener packing, material issue, and repeat purchasing should maintain the same identification relationship. For this purpose, “material issue” refers to the controlled issuance of identified fastener items for assembly, maintenance, or repeat purchasing. Bulk packing, bagging, boxed packing, labels, cartons, pallets, moisture protection, rust prevention, separation protection, packing lists, and export packing can be confirmed according to specifications, quantity, packing units, assembly identification, customer warehousing practices, and destination.How can packing, material issue, and repeat purchasing maintain the same identification relationship?
Industrial fastener packing, material issue, and repeat purchasing should maintain the same identification relationship. Bulk packing, bagging, boxed packing, labels, cartons, pallets, moisture protection, rust prevention, separation protection, packing lists, and export packing can be confirmed according to specifications, quantity, packing units, assembly identification, customer warehousing practices, and destination. Equipment model, drawing number, customer part number, original standard, specification sheet, sample photos, historical purchasing information, and purchasing lists can help identify products with the same name but different dimensions, threads, lengths, materials, property classes, or matching relationships. Historical information is used only for identification and verification; it does not replace reconfirmation for the current order.
What inspection documents can be assessed?
Material certificates, certificates of conformity, dimensional reports, hardness reports, tensile-test reports, salt-spray test requirements, and other inspection documents can be assessed according to the specific product, standard, material, property class, quantity, and customer quality requirements.
