Stainless steel fasteners for Food & Beverage Equipment.
Stainless fixings for washdown machinery and stronger duplex bolting for utility-water equipment.
Which fasteners fit your food and beverage equipment applications?
BYBOLT supplies 316L hex bolts and 316L socket head screws for external food-processing machinery exposed to washdown. Duplex 2205 stud bolts and Duplex 2205 hex bolts add strength and chloride resistance at utility-water equipment. Head style, finish and thread length follow the cleaning access and connection drawing.
Fasteners for food-processing equipment & utilities.

High-acid / high-salt sauce & brine kettles
Hot acidic brine attacks kettle flange faces and thread roots during long cooking cycles. Duplex 2205 stud sets resist pitting there while holding clamp load through repeated heating and washdown.
Duplex 2205 flange stud setsConnection requirements
- Kettle flange thickness and bolt-circle layout
- Stud thread form and engagement length
- Gasket seating load and tightening sequence

CIP / SIP (Clean/Sterilize-in-Place) spray manifolds
Nitronic 60 anti-galling nuts paired with electropolished 316L studs keep spray manifolds serviceable after repeated caustic and acid cycles. The gall-resistant pairing avoids seized threads during frequent disassembly for inspection and cleaning.
Nitronic 60 anti-galling nutsConnection requirements
- Manifold port spacing and spray-head alignment
- Stud surface finish and passivation requirement
- Disassembly clearance and nut access

Aseptic filling & dosing valve blocks
AL-6XN dome bolts offer corrosion resistance and smooth exposed heads for suitable filling-equipment joints. Sealed interfaces and accessible cleaning geometry control residue traps; the head shape alone does not eliminate crevices.
AL-6XN sanitary dome boltsConnection requirements
- Valve-block port alignment and sealing-face finish
- Dome-bolt head height and clearance envelope
- Sterilisation-cycle tightening and retorque procedure
Homogenizer & sanitary positive-displacement pumps
Electropolished 316L offers cleanable hardware for wash-water connections, while 17-4PH adds strength for compatible high-load pump attachments. Select the final condition and joint preload for the pressure cycle and actual fluid exposure.
17-4PH sanitary stud setsRelated material guides
Connection requirements
- Pump casing flange thickness and bolt pattern
- Stud material pairing and thread compatibility
- Vibration-resistant locking and preload verification method
Brewery mash tuns & fermentation manways
Warm wort, cleaning acids and carbon dioxide attack manway rims and mash-tun flanges between batches. 904L dome bolts resist that combined attack while presenting smooth, cleanable heads that limit product build-up.
904L dome bolt setsRelated material guides
Connection requirements
- Manway rim thickness and opening profile
- Dome-bolt head profile and cleanability requirement
- Seal compression and clamping sequence
Freeze-drying (lyophilization) & retort chambers
SMO 254 studs provide chloride-resistant options for compatible chamber closures, with Nitronic 60 nuts to reduce galling during repeated opening. Match the set to the vacuum or pressure load, cleaning fluid and operating temperature.
SMO 254 chamber stud setsRelated material guides
Connection requirements
- Chamber flange thickness and sealing-groove profile
- Stud length and thermal-expansion allowance
- Vacuum-seal seating and bolt-tightening sequence
Acidity, washdown and hygienic cleanability.
316L offers cleanable, corrosion-resistant hardware for many food-equipment joints. 2205, 904L and AL-6XN add options for more demanding brines; select from the food and cleaning-fluid chemistry, temperature and crevice exposure rather than vinegar or salt content alone.
What to specify
- Pitting resistance equivalent number (PREN)
- Chloride concentration in process fluid
- Service temperature band
Nitronic 60 nuts reduce galling risk during repeated opening of CIP equipment. Pair them with compatible studs and a controlled tightening procedure; surface finish, cleaning residues and any approved lubricant also affect thread wear.
What to specify
- Thread galling resistance rating
- CIP exposure frequency
- Lubricant-free assembly requirement

Smooth heads, sealed interfaces and accessible cleaning surfaces limit product-trapping crevices. 316L is a common material option, while Nitronic 60 addresses thread galling. Passivation or an alloy change cannot replace hygienic joint geometry and cleaning validation.
What to specify
- Surface roughness (Ra) specification
- Passivation standard compliance (ASTM A967)
- Head-form crevice profile

Stainless bolts, socket screws & utility studs.

316L hex bolts
Resist washdown corrosion at external tank brackets and conveyor frames, with accessible hex heads.

316L socket head screws
Fit compact packaging-machine and pump-cover joints where the drive recess remains accessible for cleaning.

Duplex 2205 stud bolts
Add strength and chloride resistance to utility-water heat-exchanger cover joints.

Duplex 2205 hex bolts

Bring external machine fixings and utility-cover hardware into one order, with head styles and finishes matched to cleaning access.
Food-equipment fastener traceability & inspection.
EN 10204 3.1 MTC, heat traceability and mechanical test results with each shipment. Add the tests your equipment specification requires.

Material identity
Match the ordered grade and material heat to the certificate, part identification and packing list.
Final condition
Link the specified processing condition and mechanical results to the finished batch; keep separate heat-treatment batches identifiable.
Drawing dimensions
Contact zone, head geometry and exposed threads.
Finish & cleaning acceptance
Mark the controlled surfaces and specify surface-finish measurements, cleanliness and packing requirements.
Before you order food-equipment fasteners.
Send the drawing and the service details for your connection. We can quote the specified parts, finish and inspection package together.
Get a QuoteDoes the enquiry need a surface-finish requirement?
Yes, where finish affects cleaning or acceptance. Mark the controlled surfaces and specify the required measurement or finish criteria rather than describing the entire part only as polished.
Can socket screws be used in washdown equipment?
They can be supplied to the drawing where the recess and surrounding joint remain accessible for the intended cleaning process. Identify the contact zone and cleaning method.
Can you supply documents for material verification?
Yes. The order can include material identification, heat traceability, mechanical results and the specified dimensional or surface checks. State any additional customer document format at enquiry.
