1/4"-20 x 1" Socket Head Cap Screws (SHCS)

Secure your assemblies with precision-engineered 1/4"-20 x 1" Socket Head Cap Screws. Designed for high-torque applications where space is limited, these fasteners offer superior strength and a low-profile finish compared to standard hex bolts. Available in four distinct material finishes, we provide the specific hardware needed to match your environmental and mechanical requirements.

Choose Your Material & Finish:

• Black-Oxide Alloy Steel: The standard for high-strength machinery. Rated at 170,000 psi tensile strength, these are ideal for internal assemblies in dry environments. (Pack of 25)
• Zinc-Plated Alloy Steel: Delivers the same 170,000 psi strength as black oxide but with an electro-zinc coating to resist rust in humid or damp conditions. (Pack of 25)
• 18-8 Stainless Steel: The go-to choice for food processing and general outdoor use. Provides excellent corrosion resistance with a 70,000 psi tensile strength. (Pack of 25)
• 316 Stainless Steel: Marine-grade protection. Infused with molybdenum to resist chlorides and harsh chemicals, making it the most durable option for saltwater or chemical exposure. (Pack of 20)

Technical Features:

• Drive Type: Internal Hex (Allen) Drive for high-torque tightening without "cam-out."
• Standardization: Meets ASME B18.3 dimensional standards and ASTM A574 (Alloy) or ASTM F837 (Stainless) material specs.
• Thread Pitch: 1/4"-20 Coarse Thread (UNC).
• This Cap Screw Requires A 3/16" Hex Key
  

Reliability Down to the Last Thread. Whether you’re maintaining factory equipment or building a marine-grade rig, TACT Industrial has the high-quality fasteners you can rely on.
