EASTLO 1/4-20 x 3/4″ Button Head Bolts
These 1/4-20 UNC button head socket cap bolts are made from 304 stainless steel with a bright finish, providing good corrosion resistance for general purpose indoor and outdoor projects. The full thread length accommodates applications requiring continuous thread engagement, while the Allen hex drive enables straightforward torque control. The set includes 25 pieces, suitable for small to medium-scale installations in furniture, equipment housings, and DIY builds. Compatibility with standard 1/4-20 hardware helps ensure a versatile component choice.
EASTLO 1/4-20 x 1-1/2″ Button Head Bolts
This longer variant shares the same stainless composition and bright finish as the shorter EASTLO bolts, with 1-1/2 inches of length for deeper threading in thicker materials or assemblies requiring stronger clamping force. The 1/4-20 thread pitch is common across many hobby and professional projects, enabling broad compatibility with existing fastener inventories. The full-thread design maximizes contact area and load distribution across the joint.
RoyceMart #10-32 x 3/4″ Button Head Screws
RoyceMart offers 100-pack stainless steel bolts with a Black Coated finish for enhanced corrosion resistance in challenging environments. The #10-32 thread size is widely used in electronics enclosures and cabinetry. The quarter-inch head and slim profile help maintain a neat appearance in assemblies where visibility of fasteners should be minimal. The fine-thread UNC pitch provides steady engagement and strong holding power in thinner materials.
VGBUY 5/16-18 x 1″ Button Head Bolts
VGBUY’s 5/16-18 stainless bolts feature high-grade 304 stainless steel with bright finishing for rust resistance in humid conditions. The 1-inch length provides robust grip in thicker panels or components, while the button head shape distributes force over a broader area to reduce material deformation. The hex drive supports efficient tightening and loosening with standard Allen keys, making these suitable for automotive, marine, and workshop projects requiring reliable performance.
SG TZH 1/4-20 x 3/4″ Button Head Screws
SG TZH provides rugged 18-8 (304) stainless steel button head bolts with a black oxide finish. The combination enhances durability in harsh environments while maintaining a low-profile appearance. These screws measure 1/4-20 with a 3/4-inch length, making them suitable for electronics enclosures, furniture fixtures, and small machinery assemblies. The black coating can help reduce glare and blend with dark-colored materials while still offering corrosion resistance.
Fullerkreg M8-1.25 x 100mm Button Head Screws
Fullerkreg offers M8 metric-thread button head screws in stainless steel (A2/304) suitable for metric-based assemblies, providing robust corrosion resistance and a clean finish. While the metric sizing may differ from typical imperial projects, many hobbyists and professionals use adapters or libraries to bridge between thread standards. The 100mm length variant addresses applications requiring deep engagement in thicker panels or assemblies with multiple materials.
MewuDecor 8-32 x 3/4″ Button Head Bolts
MewuDecor’s 8-32 x 3/4″ stainless bolts offer 18-8 (304) corrosion resistance with a bright finish. The smaller 8-32 thread is common in electronics and fine-assembly projects, where precise alignment and clean aesthetics are important. The 3/4-inch length pairs well with mid-thickness panels and components, and the 1/8-inch hex drive size supports comfortable tightening with standard tools. The low-profile head provides a neat, unobtrusive appearance.
Buying Guide
Key purchase considerations for button head hex drive screws include material, finish, thread size, length, and drive size. Stainless steel (304/18-8) provides excellent corrosion resistance for indoor and outdoor use, while black oxide finishes can reduce glare and blend with dark surfaces but may offer slightly less corrosion protection in exposed environments. Thread pitch matters for the load profile and material compatibility; coarse threads engage quickly but may loosen under vibration, whereas fine threads offer greater holding power in thinner materials.
Length should be chosen to ensure full thread engagement without protruding excessively. For enclosures and furniture, a balance between head height and aesthetic is important; button heads are low-profile and distribute clamping force effectively. Drive size, commonly 1/8 inch or 5/32 inch for standard hex sockets, affects tool compatibility and torque transmission. When selecting multiple fasteners, maintain consistency in material and finish to ensure uniform performance and appearance across assemblies.
Practical tips: match the screw material to the base material to minimize galvanic corrosion, verify the testing environment (humidity, temperature), and consider a small sample run to confirm fit before mass production. For projects exposed to moisture or outdoor conditions, prioritize stainless steel with superior corrosion resistance and a protective coating if necessary. For electronics enclosures or indoor furniture, black oxide or bright stainless options can optimize both appearance and functionality.
