Industrial Fastener References
Use this page as the main WISINE reference for industrial fastener terminology, product types, thread and size details, matched sets, material notes and RFQ preparation.
Fastener specifications, material grades, standards, dimensions, surface finishes and document requirements should be confirmed before quotation where specified by project documents.
Main Reference for Fastener RFQ Preparation
This page supports fastener terminology review and RFQ preparation for stud bolts, threaded rods, bolts, nuts, washers, anchors, special fasteners and custom fasteners.
It is a procurement-support reference. Final specification should be confirmed before production according to drawings, standards, material grade, matched components, surface finish and certificate requirements.
Confirm These Basics
- Fastener type and product standard
- Diameter, length, thread type and pitch
- Material grade and surface finish
- Matched nuts, washers or anchors if required
- Certificate availability should be confirmed before quotation
Stud Bolts, Threaded Rods and Rod-Based Fasteners
Stud bolts and threaded rods can be discussed according to material grade, thread details, length, nut and washer requirements, standards and project documents.
Stud Bolts
Confirm diameter, overall length, thread length, thread series, material grade, nut requirement and document scope.
Threaded Rods
Confirm full-thread or partial-thread requirement, cut length, material grade, surface finish and quantity.
Matched Bolting Sets
Confirm if nuts, washers, coating, marking and certificate requirements should be quoted together.
Bolts and Headed Fasteners
Bolt RFQs should confirm head type, diameter, length, thread, material grade, standard, finish, quantity and certificate requirements where specified by project documents.
Hex Bolts
Confirm product standard, size, thread length, material grade, finish and matched nut / washer requirements.
Custom Bolts
Drawing-based bolts can be discussed when standard dimensions or head styles do not match the project requirement.
Project Bolts
Project-specific bolts should include drawing, standard, material, surface finish and document requirements.
Nuts, Washers and Matched Components
Nuts and washers should be confirmed together with bolts or studs where matched fastener sets are specified. Material grade, standard, dimensions and finish should be confirmed before quotation.
Nuts
Confirm nut type, thread, material grade, standard, height, coating and matching requirement with bolts or studs.
Washers
Confirm washer type, diameter, thickness, material grade, finish and whether washers are required as part of a set.
Anchors and Installation-Related Fasteners
Anchor RFQs should define anchor type, material grade, diameter, length, substrate or project drawing notes, surface finish and document requirements where specified.
This page is not a load-rating or structural-design document. Engineering and project requirements should be confirmed separately.
Anchor RFQ Notes
- Anchor type and project drawing if available
- Material grade, coating or finish requirement
- Diameter, length, washer and nut requirements
- Application environment if material review is needed
Non-Standard Fasteners and Drawing-Based Requirements
Special fasteners and custom fasteners can be discussed according to drawings, samples, material notes, dimensions, threads, tolerance, surface finish, quantity and document requirements.
Special Fasteners
Use for non-standard shape, custom length, special thread, unusual material or project-specific fastener requirements.
Custom Fasteners
Share drawings, samples or photos when standard product pages do not define the requirement clearly.
Drawing Path
Final specification should be confirmed before production for drawing-based fasteners and custom metal parts.
Thread, Size and Dimensional Details
Thread and size information should be provided clearly in the RFQ. Standards and equivalent designations should be confirmed according to order requirements.
| RFQ Item | Details to Confirm |
|---|---|
| Diameter | Metric, inch, nominal diameter or drawing dimension. |
| Length | Overall length, thread length, grip length or cut length for rods. |
| Thread type | Metric, UNC, UNF or project-specified thread form. |
| Thread pitch | Pitch, TPI or drawing-specified thread note. |
| Head / drive | Hex head, socket, custom head or drawing-based geometry. |
| Matched parts | Nut, washer, anchor, coating and set requirements if specified. |
Material Grades, Surface Finishes and Certificate Notes
Fastener materials can be discussed according to project requirements. Material selection should be confirmed according to service environment, standard, finish, certificate requirement and application conditions.
Materials & Alloys
Review stainless steel, nickel alloys, duplex stainless steel, alloy steel, PH stainless steel, titanium and special metals.
Material Guides
Use material-family guidance to prepare safer RFQ comparisons without assuming interchangeability.
Documents
Material certificates and inspection documents can be discussed when required. Certificate availability should be confirmed before quotation.
Bolts, Nuts, Washers and Coating as a Set
Matched fastener sets should define each component, material grade, thread compatibility, coating or finish and certificate requirement. Do not assume nuts, washers or coating are included unless the RFQ states them.
Matched sets can be reviewed for stud bolts, bolts, nuts, washers and anchors where specified by project documents.
Set Details
- Main fastener type and quantity
- Nut and washer quantity per set
- Material grade and finish for each part
- Marking, packing and certificate requirements

Fastener References FAQ
What is this fastener reference page used for?
It supports terminology, product type, thread, material, matched-set and RFQ preparation before quotation.
Can WISINE discuss custom fasteners?
Custom fasteners can be discussed according to drawings, material notes, dimensions, threads, finish and document requirements.
Are load ratings provided here?
No. This resource supports RFQ preparation only. Project engineering requirements should be confirmed separately.
Should nuts and washers be listed in the RFQ?
Yes. Confirm matched nuts, washers, coating, packing and certificate requirements when fastener sets are needed.
What material details are useful?
Provide material grade, equivalent designation, standard, finish and application environment if material review is needed.
What documents should be confirmed?
Material certificates, inspection documents and order-specific standards should be confirmed before quotation.
Prepare Fastener Details Before Sending Your RFQ
Share fastener type, material grade, dimensions, thread details, matched parts, quantity, finish, certificate requirement and drawings if non-standard. Availability is subject to material availability, quantity, processing requirements and document requirements.
