COMPONENT REQUIREMENTS

Screw-down nut blank

Define the geometry, material, delivery condition and acceptance criteria for the selected application. Manufacturing scope requires review of the approved drawing and operating requirements.

COMPONENT GUIDE

Screw-down nut blank

Load-carrying nut around a mill screw-down or roll-gap adjustment screw.

Provides the blank for the specified adjustment nut and its agreed machining operations.

Manufacturing & delivery form
Block or cylindrical casting blank with agreed premachining; finished threads specified separately.

Blank supply does not establish adjustment-system accuracy. C86300 remains a material candidate until approved for the actual nut, load and lubrication conditions.

Material candidates

UNS C86300 Manganese brass / manganese bronze

Candidate for specified heavily loaded sliding parts and nut blanks.

A high-strength brass family, not tin bronze. Confirm the counterface and lubrication; no universal wear-life claim applies.

UNS C95400 Aluminium bronze

Candidate for drawing-defined loaded sliding and wear components.

Review mating material, lubrication and supply condition. C95400 and C95800 are distinct grades.

Confirm the drawing, actual duty, material standard and manufacturing condition. Material substitutions require customer approval, and supply scope is agreed after component review.

Component RFQ requirements

Nut definition: Body envelope, weight estimate, thread design and engagement.
Mating screw: Screw material, thread form, alignment and specified backlash.
Load & lubrication: Adjustment loads, cycle, lubricant and actual part temperature.
Machining plan: Stock allowance, datums, thread-machining responsibility and inspection.
Material & acceptance: Specified alloy and standard, supply condition, drawing revision, quantity, inspection criteria and required records.
Supply form: Block or cylindrical casting blank with agreed premachining; finished threads specified separately.

Start with your drawing, specified alloy and quantity. Include the required delivery condition and acceptance records so the manufacturing and inspection scope can be reviewed.
