Product Overview
These M8 hex socket set screws are shown as headless, fully threaded cylindrical fasteners with an internal hex socket. They are intended for positioning or securing a hub, collar or similar component through a mating threaded hole rather than for use as cross-head or Torx self-tapping screws.
For a B2B quotation for M8 hex socket set screws, provide thread pitch, length, end style, socket requirement, mating hole, shaft or contact surface, drawing or approved sample, material, finish, quantity and packaging. Verify contact and holding function in the actual assembly.
Procurement note: Specify M8 pitch, screw length, end style, socket size, mating threaded hole, shaft or hub material, finish, quantity and packaging.

Applications
Shaft collar positioning
Confirm collar thread, shaft diameter, contact surface, end style and required positioning function.
Gear and pulley hubs
Check threaded-hole depth, shaft contact, key or flat geometry and access for the hex key.
Adjustable fixtures
Define adjustment frequency, seating point, surrounding clearance and any buyer-specified functional criterion.
OEM maintenance packs
Counted set-screw assortments can be reviewed after each size, length, pitch and pack quantity are approved.
Buyer Guide: How to Choose
How should the set-screw length be chosen?
Compare threaded-hole depth, required shaft contact, adjustment range and clearance; confirm the drawing datum and complete an assembly trial.
Which end style should be specified?
The image shows a flat end. State whether flat, cup, cone or another end is required and define the mating surface and functional purpose.
Can the M8 pitch be customized?
Yes. Provide the mating hole or gauge, pitch, tolerance, drawing or approved sample for review before production.
What socket information is required?
Confirm hex size, socket depth, tool access and any buyer-defined drive-fit requirement from the drawing or sample.
Quality Control
Inspection scope should be agreed against the approved drawing, sample and purchase specification. For screws, the review focuses on dimensions, thread, drive fit, finish and assembly performance.
M8 thread and pitch
Use the agreed thread gauge or mating hole to verify size, customized pitch and fit.
Length and end geometry
Check length datum, overall length, end style and contact face against the approved drawing.
Hex socket engagement
Use the agreed key or gauge to review socket size, depth, engagement and tool access.
Hub or collar trial
Verify installation depth, shaft contact and positioning function in the confirmed assembly when included in the control plan.
Finish and packaging
Inspect visible finish, size segregation, pack count, labels and carton identification as specified.
If salt-spray, torque, pull-out or another performance test is required, include the test method and acceptance criteria in the RFQ for feasibility review.
