Stainless Steel 5/16-18 Hex Flange NutWBB2264426Secure compatible threaded connections
Use standard hex nuts with compatible bolts, screws, studs, threaded rod, and machine-threaded fasteners for assembly, maintenance, repair, and installation work.
Match the thread before selecting
Choose the exact thread required, such as #6-32, 1/4-20, 5/16-18, 3/8-16, 1/2-13, or 5/8-11. Then confirm the specified grade, material, finish, and package count.
Select the nut form for the job
Finished hex nuts support general threaded fastening. Flange nuts provide a broader bearing surface, serrated flange nuts add a serrated bearing surface, and coupling nuts connect compatible threaded components.
Consider material and installation needs
Available choices include carbon steel, stainless steel, zinc-plated, zinc CR+3, zinc yellow CR+6, and black oxide finishes. Sleeve anchors with hex nuts are intended for securing fixtures to concrete, block, brick, or stone.
Options include machine-thread and UNC sizes for compatible fastening components.
Choose a quantity suited to installation, repair, assembly, or shop inventory needs.
Finished hex, flange, serrated flange, coupling, and sleeve-anchor options are available.
Select threaded nuts for compatible fasteners or sleeve anchors for concrete and masonry fixtures.
Compare Hex Nut Types
Use this overview to identify the product type that matches the connection and bearing-surface needs described in the product summaries.
| Product type | What it is used with | Notable listed feature |
|---|---|---|
| Finished hex nut | Compatible bolts, screws, studs, threaded rod, and machine-threaded fasteners | Standard hex form; available in multiple thread sizes, grades, materials, finishes, and pack counts |
| Flange or serrated flange nut | Compatible threaded fasteners | Integrated flange provides a broader bearing surface; serrated versions include a serrated bearing surface |
| Coupling nut or sleeve anchor with hex nut | Compatible threaded components, or fixtures installed in concrete and masonry | Coupling nuts connect threaded components; sleeve anchors use an expanding sleeve and through-fixture installation |
Plan the right fit before choosing
Match the nut to the threaded fastener
Thread compatibility is the first selection point. The products represented include UNC and machine-thread sizes ranging from #6-32 through 5/8-11.
- Match #6-32 nuts to compatible #6-32 machine-threaded fasteners.
- Select 1/4-20, 5/16-18, 3/8-16, 1/2-13, or 5/8-11 only for compatible threaded components.
- For sleeve anchors, confirm the required 5/16 in. x 1-1/2 in. anchor size and the installation surface.
Choose a design that fits the fastening task
Standard finished hex nuts have a conventional hex form for tightening and removal. Specialized designs address different connection needs without changing the need for compatible threads.
- Flange nuts have an integrated flange that provides a broader or wider bearing surface at the fastening point.
- Serrated flange nuts have an integrated flange with a serrated bearing surface.
- Coupling nuts are designed to connect compatible threaded components.
- Sleeve anchors with hex nuts use an expanding sleeve and allow through-fixture installation in concrete, block, brick, or stone.
Align the hardware with the stated requirement
Compare the material and grade called for in the fastening work, then select the listed finish and quantity that suit stocking, assembly, replacement, or installation needs.
- Grade 2, Grade 5, Grade 8, Grade A steel, and 18-8 stainless steel options are represented.
- Stainless steel options include 18-8/304 and 18-8 (A2); certain 18-8/304 products provide corrosion and chemical resistance for demanding environments.
- Listed finishes include zinc plating, zinc CR+3, zinc yellow CR+6, and black oxide.
- Pack quantities represented include 25, 50, and 100 pieces.
Common questions before buying
How do I choose the correct hex nut thread size?
Match the nut exactly to the compatible threaded fastener. Sizes represented include #6-32, 1/4-20, 5/16-18, 3/8-16, 1/2-13, and 5/8-11.
What is the difference between a finished hex nut and a flange nut?
A finished hex nut has a standard hex profile. A flange nut has an integrated flange that provides a broader bearing surface at the fastening point.
When should I consider stainless steel hex nuts?
Choose a listed stainless steel option when the fastening requirement calls for 18-8/304 or 18-8 (A2) stainless steel. Certain 18-8/304 options provide corrosion and chemical resistance for demanding environments.
What are sleeve anchors with hex nuts used for?
They are used to secure fixtures to concrete, block, brick, or stone. Their expanding sleeve distributes compression load over a longer length for use in soft concrete, and they allow through-fixture installation.
