SKU CH-XY50-RJ1BH

Alloy steel cup-point set screws with 6-32 thread and 1-inch length in a 100-piece pack

  • Cup point design ensures secure grip on shafts
  • Black oxide finish resists corrosion effectively
  • Class 3A threads guarantee precise fit
  • Pack of 100 covers large projects efficiently

Socket Set Screw Cup 6-32 x 1 Inch

This pack contains one hundred alloy steel socket set screws with a cup point and coarse 6-32 threads. Each screw measures one inch in overall length and features a hex socket drive sized at 1/16 inch. The black oxide finish provides corrosion resistance for general fastening tasks. Rockwell hardness falls between C45 and C53.

Coarse Thread Cup Point for Secure Locking

The cup point design digs into the mating surface to resist vibration loosening in fixtures or machinery. A 1/16 inch hex key drives the fastener without external head clearance. Class 3A threads ensure a precise fit in tapped holes. The 0.074 inch point diameter concentrates holding force on shafts or collars.

Replaces Worn or Stripped Set Screws in Assemblies

Use this bulk pack to replenish maintenance stock for equipment using 6-32 coarse threads. The alloy steel construction upgrades from softer fasteners that deform under torque. Buyers needing fine-thread pitches or longer lengths must source different specifications. The PK100 quantity suits high-volume repair shops.

Questions about this item

How long before the 1/16 in. hex socket on these cup-point screws rounds out under daily use?

The 1/16 in. hex drive is cut to Class 3A tolerance on alloy steel hardened to Rockwell C45-53, so the socket walls resist stripping far longer than standard-grade screws when driven with a correctly sized key.

Do the black-oxide 6-32 screws gall or seize when left tightened in a hot engine bay for months?

Black oxide adds a thin conversion layer that reduces galling compared to bare alloy steel, and the cup point concentrates clamping force without digging threads, so they release cleanly after extended heat cycles.

What size hex key is needed to install the 100-piece pack of 6-32 x 1 in. cup-point set screws?

A 1/16 in. (0.062 in.) hex key fits the socket drive on every screw in the pack.
