Iexcell 100 Pcs SAE 6-32 Screws Set
The iexcell assortment includes multiple lengths (1/4″, 3/8″, 1/2″, 5/8″, 3/4″) in a 12.9 grade alloy steel with a black oxide finish. Each screw uses a socket cap head with a hex drive, designed for applications requiring a flush profile and solid torque. The broad length range supports hobby projects and light-duty mechanical assemblies, while the 12.9-grade steel provides robust strength for common fastener tasks.
VAMUOEFL #6-32 x 3/8″ Socket Head Caps
These 304 stainless steel screws offer corrosion resistance and a black exterior finish. They feature a full machine thread and an Allen hex drive, suitable for precise assemblies where a sleek appearance and resistance to rust are important. Each 3/8″ length aligns well with mid-thickness components or enclosures that require moderate thread engagement.
#6-32×5/8″ Socket Head Cap Screw, 304 Stainless
This product provides a longer 5/8″ length in a fully threaded, 304 stainless steel socket head cap screw. With a 0.226″ head diameter and 0.138″ head height, it offers strong engagement and reliable torque for electronics enclosures or small mechanical housings. The 32 TPI thread pitch ensures stable fastening with the 6-32 thread size.
NIULUNBAO 100Pcs 6-32 Assortment Kit
The NIULUNBAO kit covers lengths from 1/4″ to 3/4″ in a bright machine finish. It combines 6-32 sockets with a 32 TPI thread pitch and an Allen drive, providing a versatile option for hobbyists needing a broad range of fasteners within a single package. The assortment approach can simplify projects with varied thicknesses and material types.
ZDingTech 50Pcs 6-32 x 3/8″ Set Screws
ZDingTech offers 50 pieces of 6-32 x 3/8″ stainless set screws in a complete kit with a 1/16″ Allen wrench. These are cup-point, headless screws designed to sit flush with the surface when fully installed, making them suitable for applications requiring a smooth profile or concealment within equipment housings. The 304 stainless steel construction provides corrosion resistance in challenging environments.
Buying Guide: Key Considerations for 6-32 Allen Head Screws
- Material and corrosion resistance: Stainless steel (304/18-8) offers excellent rust resistance for electronics, outdoor equipment, and humid environments. Alloy steel with a black oxide finish can provide added hardness and a distinct appearance for metalwork where corrosion is less of a concern.
- Length and threading: Ensure the thread length matches the material thickness and the intended mounting surface. Full-threaded designs provide stronger tying across the entire shank, while partial-threaded or cup points can be beneficial for self-centering or flush installations in softer substrates.
- Head style and drive: Socket head cap screws with hex drives deliver strong torque transfer and a clean, low-profile look. Button head variants are lower-profile but offer less engagement surface. Confirm the appropriate head height and diameter for your enclosure or panel.
- Finish and appearance: Black oxide finishes are common for aesthetic reasons and some corrosion resistance, while bright stainless finishes emphasize visibility and clean metalwork. Choose based on visibility, environmental exposure, and compatibility with other fasteners.
- Quantity and packaging: Kits ranging from 50 to 100+ pieces suit hobbyists and technicians who work across multiple projects. If only a single size is needed, consider focused sets to avoid oversupply or confusion.
- Compatibility and standards: The 6-32 thread size is widely used in electronics enclosures, camera rigs, and small assemblies. Verify the exact thread pitch (32 TPI) and head dimensions to ensure proper fit with your parts and tools.
Across these options, you will find choices that balance strength, corrosion resistance, and value. For electronics and DIY projects, stainless steel variants often provide the best balance of durability and appearance, while alloy steel batches with black oxide finishes can be ideal for heavier mechanical tasks where appearance is less critical. Always verify the length, diameter, and drive type to match your project requirements.
