Value Collection 3SSC908F0204 Hex Head Cap Screw 1/2-20

Product Description

The VALUE COLLECTION 3SSC908F0204 is a partially threaded hex head cap screw designed for general mechanical and structural fastening applications. This fastener features a 1/2-20 UNF thread form — a fine-pitch thread well suited to applications requiring precise thread engagement or resistance to loosening under vibration. The screw measures 2-1/4 inches in length under the head and is manufactured from Grade 18-8 stainless steel with no coating applied. The hex drive measures 3/4 inches across flats, accepting a standard hex wrench or socket. At 0.15 pounds per unit, this screw is a lightweight yet durable fastening solution for trade and industrial use.

This cap screw is appropriate for use in plumbing, HVAC, electrical panel work, equipment mounting, and other mechanical assemblies where corrosion resistance is a priority. The 18-8 stainless steel construction makes it suitable for moist or mildly corrosive environments. The partially threaded shank provides a smooth bearing surface against the clamped material, which is preferred in many structural or load-bearing joint configurations. A minimum order quantity of 5 pieces applies to this SKU.

Key Features

• 1/2-20 UNF fine-pitch thread for improved vibration resistance and precise torque control
• Partially threaded shank provides a clean bearing surface in clamped joints
• Grade 18-8 stainless steel construction resists corrosion in wet and mildly harsh environments
• Uncoated finish — no risk of coating delamination affecting thread fit
• 3/4-inch hex drive accepts standard hex sockets and wrenches

Compatibility

Designed as a standard 1/2-20 UNF hex head cap screw suitable for use wherever a partially threaded, Grade 18-8 stainless steel fastener of this thread size and length is specified.

Installation Notes

This fastener is installed by a mechanic, pipefitter, HVAC technician, or electrician using a 3/4-inch hex socket or open-end wrench. De-energize or shut down the equipment being serviced before replacing any fasteners in live assemblies. Apply thread lubricant or anti-seize compound per the equipment manufacturer's guidance when working in high-moisture or dissimilar-metal environments. Follow applicable torque specifications from the equipment service documentation or relevant code — do not over-torque stainless steel fasteners, as the material is susceptible to galling.
