Kerr Lakeside 10-32 x 1 in Button Head Cap Screw 100 Pieces

SKU CH-CBQK-4NFKX

Alloy steel button head cap screws with 180,000 psi tensile strength and Rc 38-43 hardness, ASTM A574 compliant, 100 pieces

  • Button head design allows low-profile installation
  • Alloy steel construction rated to 180000 psi tensile strength
  • Rockwell hardness Rc 38-43 resists stripping under load
  • Black oxide finish meets ASTM A574 and ANSI B18.3 standards
  • 100-piece pack supplies volume for production or maintenance tasks

10-32 x 1 in Button Head Cap Screws

These alloy-steel button head cap screws come in a pack of 100 pieces. They are designed for general fastening tasks that require a low-profile head and a hex drive. The black oxide finish provides mild corrosion resistance. They suit mechanics, fabricators and maintenance crews who need a ready supply of fine-thread fasteners.

Capacity and headroom: 180 000 psi tensile strength

Each screw is rated to 180 000 pounds per square inch tensile strength with a Rockwell hardness of 38 to 43. The full-thread, 1-inch length handles typical clamping loads in steel or aluminium assemblies. They are not suited for structural joints that demand higher-grade hardware or for applications requiring a longer grip length.

Deciding spec: 10-32 UNF fine thread

The 10-32 unified fine thread is the single detail that determines fit. It only mates with matching 10-32 tapped holes or nuts; it will not engage coarse-thread or metric counterparts. Verify the thread callout before ordering to avoid mismatched hardware.

Questions about this item

Will these 10-32 x 1 in button head cap screws fit into existing UNF fine-thread holes I already have?

Yes, they use a standard UNF 10-32 right-hand thread, so they match any correctly tapped UNF fine-thread hole of the same callout size.

How can I verify the 180000 psi tensile strength and Rockwell hardness after installation?

The screws meet ASTM A574 and ANSI B18.3 with a Rockwell hardness of Rc 38-43; a calibrated hardness tester or tensile test lab can confirm the values.

Does the 100-piece pack include any hex keys or drivers for the hex drive?

The box contains only the 100 alloy steel button head cap screws with black oxide finish; a 10-32 compatible hex key must be purchased separately.
