90 Piece #8-10 Hex Socket Set Screw Assortment Starter Kit
90 socket set screws in an 18-hole labeled plastic drawer — #8, #10, 1/4", and 5/16" sizes in multiple lengths, covering the most common set screw applications in pulleys, couplings, collars, and gear hubs. Set screws are headless — they sit flush or below the surface after installation, making them the standard solution wherever a protruding head would catch on rotating machinery or moving components.
What's Included
- Hex socket set screws (cup point) — #8, #10, 1/4", and 5/16" in multiple lengths per size
- 18-hole labeled plastic drawer — pre-sorted by size and length
- 90 pieces total
Specifications
| Drive type | Hex socket (Allen/hex key) |
| Point style | Cup point (standard) |
| Sizes | #8, #10, 1/4", 5/16" |
| Thread standard | UNC (coarse) |
| Material | Alloy steel, black oxide or zinc (case-hardened) |
| Total pieces | 90 |
| Storage included | Yes — 18-hole labeled plastic drawer |
Best For
- Machine shops and mechanical service — set screws are consumed whenever a pulley, collar, or coupling is removed and reinstalled; having common sizes in a labeled bin prevents hunting through loose hardware
- Industrial maintenance teams — conveyor systems, motors, gearboxes, and pumps all use set screws to locate components on shafts; a stocked assortment keeps routine maintenance moving
- HVAC and fan system technicians — blower wheels, fan hubs, and sheaves are secured to shafts with set screws; the #10 through 5/16" range covers the most common HVAC shaft sizes
About Hex Socket Set Screws
Set screws (also called grub screws) are fully threaded headless fasteners driven with a hex key (Allen wrench). They thread into a tapped hole in a hub or collar and press against the shaft to lock the component in position. The cup point (concave tip) is the most common point style — it bites into the shaft surface slightly under torque, creating a mechanical lock that resists rotation and axial movement.
Other point styles (flat, cone, dog) are used in specific applications: flat point for softer shafts where marking is unacceptable, cone point for permanent locking, dog point when the shaft has a flat or groove for positive engagement. This kit stocks cup point as the standard workhorse.
Always torque set screws to the manufacturer's specification — under-torqued screws will back out under vibration; over-torqued screws will strip the socket or damage the shaft. Questions? Contact us.
