This includes self‑drilling screws, standard hex head bolts, and some hex washer head screws. For best results, measure your hex head’s width before ordering.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-item\"\u003e\n\u003cdiv class=\"hdiy-faq-question\"\u003eAre these caps truly waterproof, or just dust covers?\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-answer\"\u003eThey provide a very good water seal for rain, splashing, and hose spray. The cap snaps tightly around the hex head, creating a physical barrier. However, they are not designed for submerged applications (e.g., underwater bolting). For maximum waterproofing in driving rain, adding a dab of silicone inside the cap is recommended.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-item\"\u003e\n\u003cdiv class=\"hdiy-faq-question\"\u003eWhat temperature range can these plastic caps handle?\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-answer\"\u003eThey are rated from approx. -20°C to +80°C (-4°F to 176°F). The plastic remains flexible in cold weather (won’t become brittle) and resists softening in normal summer heat. For extreme high‑temp environments (like engine compartments), consider silicone caps instead.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-item\"\u003e\n\u003cdiv class=\"hdiy-faq-question\"\u003eCan I reuse a cap after removing it?\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-answer\"\u003eYes, usually. The snap fit may loosen slightly after repeated removals, but for occasional access (like seasonal maintenance), they can be reused several times. For permanent sealing, it’s best to use new caps after removal.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-item\"\u003e\n\u003cdiv class=\"hdiy-faq-question\"\u003eDo you offer these caps in colors other than black\/gray?\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-answer\"\u003eMost stock is black or gray to blend with roofing and hardware.
