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.
